Q: mike waaaaah! now look youve gone and made me cry! i was hoping though but i know that ive had the code for a lot longer than the seriously rusty muffler. how often does it run these self-tests so youre saying i shouldnt reboot my truck after its fixed i should wait and see if the code goes away on its own jmc either way. if the tech clears the code after the repair and the light doesnt come back on voila! if the repair is made and the light goes off after several days of driving voila again! the self=test isnt performed at each start up. an obdii drive cyle must be completed before the self-test runs... usually a couple or three days of normal driving will do the trick. mike thanks. the light hasnt come back yet ive driven about 40 miles today its been started three times. ill keep an eye on it. worse though i think my engine started knocking! noise is in the right side of the engine block as i face the truck a tickticktick noise at about two ticks per second. i noticed it as i arrived home today. can only hear it at idle. shut the truck off went back out just now about an hour or so after turning the truck off. turned it on no tick. as soon as i revved the engine a little though the tick started again. i suspect it starts when the truck gets warm. its not really loud but can be heard inside the cab when the windows rolled down. knock is serious isnt it i just had the sparks replaced not two months ago. i dont understand why it started up right after an unrelated repair dammit!. how hard is this going to be to fix and is it going to cost a lot is it ok to drive it for short distances until repaired help appreciated! jmc ok before everybody jumps off the deep end lets look listen to the noise. is the ticking variable with the engine rpm or does the ticking remain at a constant frequency regardless of the engine rpm if it is constant regardless of the engine rpm it is likely an evap purge solenoid doing its job. it will make a ticking noise as it recycles fuel vapors back into the engine. if the ticking noise is variable with the engine is it possibly a fuel injector. these little guys are like the water valve in your automatic washer and make a normal ticking sound as they operate. take a long screwdriver and put it against a fuel injector you have eight of them and place your ear on the other end of the screwdriver... is this the noise you are hearing. btw do the screwdriver thing while no body is looking or theyll think youve gone nuts. does the ticking only occur on cold start up and then goes away after the engine is warmed up this could be a small crack in the exhaust manifold that seals itself as the manifold expands with heat. another possibility is that when you last changed the oil a poor quality filter was used that doesnt have an anti drain back valve and what you are hearing are the lifters until they refill with oil. the bottom line is that there are many many things that can make the noise you are talking about... most of em not very serious. an engine that is failing usually does so gradually and has other warning signs so i would not panic just yet. let me know if any of this helps. mike well i feel better eddicated anyway took the truck back to twig today. he used a piece of rubber hose listened here listened there listened while revving the engine a bit. heres what i heard while he was doing that when the truck was cold i heard no ticking but then i didnt pop the hood. when the engine is revved i could sometimes hear it have what i can only call an arrhythmia my heart does that sometimes before i stopped hearing it. its really hard to say im not sure but it didnt seem to get more rapid its more like it got... erratic but maybe faster too. but not fast as in keeping pace with the rpms. does that make sense not sure if it stops at that point or if it cant be heard over the engine. with all this careful listening it seemed to me that it wasnt a metal-on-metal noise sounded more... airy. the ticking gets worse as the engine warms up so it might have been ticking at cold but it definitely gets more pronounced as the engine warms up. to me when standing on the drivers side it sounds like the tick is coming from just back of center of the main engine body down low below the sparks. this would sort of jive with what luck twig wasnt having he seems to agreed with that as he wasnt getting an exact location with his bit of rubber hose from above. theres a good quality oil filter on i cant remember if its a k&n or a bosch. i havent tried the screwdriver thing. should i still based on the above. ok so before you read the next line what do you think it is still dont know.... the not changing rythm with engine rpm leads me to believe its not an exhaust leak... but sigh who knows.... . . . . . . . twigs tak

teribble insecurity you must have. ----------------- thesnoman.com . 222 337873 5hlfssf3ki0iru1@mid.individual.net suddenly without warning mike simmons exclaimed 7/31/2007 750 pm had my truck in for service today as the muffler was rusted through and the rest of the system didnt look too good either. since i had it in to an exhaust expert i had them look for the cause of the p0455 code evaporative emission control system leak detected no purge flow or large leak. ive had codes for this system for years it started with the p0422 code then changed to p0455 6 months or more ago. ive been ignoring it as theres been no driveability issues. the exhaust system will not cause that code. the check engine light will i fear return. your truck is equipped with an obd ii diagnostic system that performs periodic self tests. after three good self tests the check engine light will turn itself off. thus if the problem was no longer there the light would have self extinguished by now. sorry to be the bearer of bad tidings. mike yup light came back on today. does it tell us anything that the light didnt come back on until id been to the gas station it was off when i stopped. got gas light came on when i turned the truck back on. as has been the case for some time there was no release of pressure when i removed the gas tank. and before anybody mentions it i replaced the gas cap fairly recently. jmc .

hi folks looking for info from anyone that does emission inspections i massachusetts especially if they have any experience with modde obdii vehicles or input from anyone that has been through an similar transmission/pcm obdii swaps in massachusetts this subject is probably nowhere near as complicated as i making it out to be here but i have a couple of pcm swap question that i cant seem to resolve. the project - put a 5spd nv trans in my 98 5.9 zj jeep. figure the easiest way is to use a pcm from a 98 5.9 5spd ram. done extensive googling on the subject and done search/faq o about two dozen dodge/jeep/mopar forums. ive found out a lot but th info doesnt always agree from site to site and/or im not sure i other peoples experience applies to the type of emission inspections we do here just came back from the place i got my sticker last time and h couldnt answer all of my questions off the top of his head because h had never seen anything similar done. my vehicle is still stock a the moment the answers to all of these individual questions arent a important as the whole idea of whether it can be done or not and ho and what actually comes into play so the main questions 1 - do all states have the same emissions/inspectio requirements as massachusetts now that obdii is around if not wha other states do 2 - the emission inspection machines in ma reads the vi through the obdii port correct does the tech also have to manuall enter the vin and/or verify that it agrees with the pcm vin 3 - any cel/code will automatically fail a vehicle through th machine yes 4 - if a vehicle has cel/codes due to the missing auto trans i there any option in the machine for the tech to override or ignore th failure that wouldnt really apply since it wouldnt have th automatic in it anymore 5 - the best way around this is to use the pcm from a 5.9/5sp ram 6 - can a new vin be flashed into a used pcm or not chrysle dealer says they cant do it but im not sure if thats a the wont do it issue or a they actually cant do it issue. someone said the enter vin option doesnt come u on the drb if the pcm already has a vin 7 - if the vins cant be easily overwritten used pcms wouldn have any value right maybe for use in non-inspection states 8 - do any digits in my vehicles vin specify the transmissio type i dont think so if they do - maybe im getting too craz here - does that figure of the vin actually have any input as to ho the pcm operates or is the vin flash just an interna label 9 - do any other scanners have the ability to overwrite vins o delete them 10 - i know b&g charges $130 for vin flash and $430 for custom flash. is overwriting the vin considered custom 11 - can my 5.9/auto trans pcm be reflashed deep enough t eliminate the looking for auto trans inputs i talked t b&g about this swap but it was at about 459 on a friday. didnt have the heart to keep them there answering questions about swap that probably had them questioning my sanity anyway - 12 - do the ram trucks have bcms and is that a factor in thi swap 13 - the alarm/disable issue - vtss ive heard the pcm fro a factory alarm vehicle can only go into another factory alar vehicle. a non-alarm pcm can go into either one ill try b&g again sometime soon but figured id post her first to see if anyone had any experience with similar swaps in mass besides i think most performance flashes are designated for of road use only so they may not take these inspection issues int account like i said so much info/so many conflicting answers. i kno there can be issues with the seatbelt warning lights and/or the ab lights etc others say thats not a problem as long as the pcm ha any vin number in it the nuts and bolts of the swap isnt that crazy but i don want to start buying parts til i solve the last few issues. thanks for any replies - johni note the at the endof you post but opto-isolators and odbii i dont see why it wouldnt work but i have only seen copper. im not a professional service technician which makes me curious do anyvehicles us opto-isolatorssorry you mean thats a real thing and he wasnt pulling my leg soundedlike some of the made up stuff we used to say to confuse thenon-mechanics around us. gotta admit if its a real thing ive never even heard of it. ill google it later as i have to run out now.all i can say is whatever an opto-isolator is it sounds expensive!- .
