Code 43 has returned :(
From : Annonymous
Q: shop idling in gear and you can see the misfires counting up 810 in the course of a couple minutes all on #7. the only code being set is p0307. while this is happening misfires counting up if you give it a slight bit of throttle do the misfires go away .

aarcuda69062 wrote dlc dlc@dlc.net wrote dlc writes if i unplug the sensor and turn the ignition on the gauge reads low all the way to the left. if i short the lead still unpluggedto ground the gauge reads high all the way to the right. so i am confident i am dealing with the coolant sensor. it is just behind the alternator. the service manual suggests the correct resistance should be between 10k and 13k at 70 degrees. the sensor reads 2k. i havent checked the sensor with the engine warm. i know this seems backward and the gauge should read high but 2k is not a normal reading so i thought i would change out the sensor. by the way the temperature gauge has read low since i bought the vehicle last year. the only reason i am concerned is that i am still having stalling and backfiring problems and have replaced the catalytic converter muffler distributer cap and rotor spark plugs ignition wires o2 sensor fuel filter air filter and egr valve. i have also checked for vacuum leaks. so i am trying to fix anything that is possibly related. the backfiring occurs when i am driving at a constant highway speed and encounter a hill. as i gently apply more throttle to maintain the speed the engine will briefly stall and backfire through the exhaust. if i let off the gas for a few seconds the engine will begin to run smoothly and everything seems normal. on a 400 mile trip this may happen 2-3 times. any ideas why are you screwing around with the sender for the dash gauge in order to solve a driveability problem as for ideas; you might want to check the distributor for worn out bushings. dlc writes i believe that the coolant sensor is one of the inputs the computer uses in setting the timing but you are right that i am probably wasting energy with this. i will check the distributer bushings and the distributer position sensor as well. thanks .

any tips for r&r or is this a shop job real simple - its on the back of the throttle body. two torx screws and an electrical connector. while youre at it just remove the whole throttle body four bolts from the top once you take the air cleaner off strip off the iac the map sensor and the tps sensor all remove the same - just a couple of screws then give it a good thorough cleaning with some tb cleaner. when you put it back together leave the iac uninstalled. plug the electrical in and while holding it have someone turn on the ignition but dont start the truck - it will rev to redline! and watch the movement of the iac pintle. it should cycle all the way out then all the way in then settle to a position somewhere in the middle. this should all be smooth movements. if its not or if in doubt you can try cleaning it as well but a replacement isnt that much money either. before embarking on this pick up a new throttle body gasket - 50% chance youll trash the old one while removing the tb. .

i just went through a similar experience and found that one of my engine valves was running right at the end of the range of a hydraulic lifter and as the engine got hot stopped the exhaust valve from totally closing causing a misfire. ended up taking that engine apart twice. the second time took .025 off the end of the valve and problem went away. yes before i did this i replaced the idle air control motor which didnt help at all. i also was going to replace the map sensor before i determined it might be a valve but didnt so saved that $50. after the second assembly i ended up with a tappet noise but found i had only installed it backwards so it didnt have chance to pump up. 5 weeks later i believe i might have an engine that will go another 75000 before it will need much work. good luck ron ramman@dodgecity.cc wrote its back and this time back with a vengance. p0307 cyl #7 misfire those who have followed my plight know this saga began a year or more ago. various things at various times have solved or rather mitigated the problem to a greater or lesser extent for a while but this time its back and not quite but almost a steady-state hard failure. clearing the code and it comes right back within the first 510 miles of town driving. 97 ram 1500 5.2l 80k miles work done over the past year to date all mopar parts new coil new plugs new wires new rotor cap plug wire rerouting tsb applied flushed injectors several times cleaned combustion chamber checked compression 135144 lbs all cyls 52.8 psi fuel pressure swapped #5 & #7 injectors problem stays on #7 problem seems to occur most often when decelerating from 2530 mph to a complete standing stop in gear i.e. approaching and then sitting at a light with your foot on the brake. all of a sudden you feel a faint flutter in the idle and 10 secs later the mil lamp is on. sitting in the shop idling in gear and you can see the misfires counting up 810 in the course of a couple minutes all on #7. the only code being set is p0307. what next doctor .

philip mc wrote are you sure that your transmission is shifting through all the gears i think thats what it is. i originally thought it wasnt the tranny because i was reaching highway speeds smoothly but as i pay more attention to the sound and feel of the engine i think im missing top gear. this on a rebuilt transmission thats less than two years old but out of warranty of course. - its in the shop now. .

interesting you should ask. in fact they do. the misfires appear to be happening at loaded idle idling in gear. checked/cleaned/replaced the idle air control motor .

the splash guards were not the problem i had the chrome wheel well trims installed by dodge and they were not mopar parts. so dodge wont do anything i have to afte the dealership. so this afternoon i talked to the shop foreman and he is still waiting to hear from dodge. here in sask they mix salt and sand in the city for icy streets. inside the moulded mud flaps they were have filled with sand. this was far down enough that it did not touch any paint. i would recommend anyone who has any trims on to take them off now and then to clean out any cunk. dale simmons mikesim@yhti.net wrote yonzie the mopar molded splash guards come with screws that have a sealer on the threads to prevent this very thing from happening. i would mention this to the dealer and he should mention this to their rep as well. if you would have installed aftermarket splash guards i would say you are on your own but since you installed mopar accessories they have an obligation to help you out. mike my 2003 has rust. i had chrome wheel well covers put on by the dodge dealership where i bought the truck new. also had moulded dodge mud flaps put on.put these on to protect the truck from stone chips. just a couple weeks ago i took of the flaps off to clean them. some sand got trapped inside the flaps and washed them. then i decided to take the chrome wheel well covers of to see if anything needed cleaning. found the paint was bubbling and peeling in two spots. about the size of a silver dollar. where the holes were drilled to fasten the mouldings the paint around them was rusting. my local dodge dealer who didnt sell me the truck took pictures of this and sent them out to the area rep. they tell me on thursday that dodge will not fix the rust. its not the fault of the truck. the installation of accessories is not covered. so who ever drilled the holes to install the guards will have to cover the problem. had two estimates to have the four fenders pained about $1300. now the shop foreman where i bought my truck at dodge city in saskatoon is going to talk to the same area rep. i know dodge will tell him its not the trucks fault that the holes should never been drilled. question is dodge sells these mouldings through parts so how are you suppose to install them screws come with them. anyhow i know im going to be stuck with the painting. got to get it fixed can not have it get worse. im going to get the truck painted even if i have to pay for it. so anybody out there dont put those moulding on. salt and sand gets between them and the paint. friday went out and drove a 2005 ford f250 crewcab. very nice riding truck. might have to go monday and price it out. dodge has really disappointed me after 5 dodge trucks maybe time to switch. dale .
