Engine sometimes stalls after starting -- can it be battery related

Q: no they are not the same thing. the tb or throttle body controls the amount of air entering the intake manifold. yup. a tb spacer fits between the throttle body and the manifold with the idea of smoothing out the airflow perhaps but more likely its to add length to the intake tract in an effort to get more low end torque. not that it always works thta way. smoothing air flow by adding a second mating point seems a bit odd. better idea is to use something that will produce laminar air flow which could be added with the spacer but usually is not. into the intake for better fuel atomization and allowing more air to get into the cylinders. atomization perhaps yes. more air into the cylinders nope. as you just said the tb regulates that not the spacer. while the tb regulates air flow that flow is ultimately limited by the efficiency of the intake system as well. the spacer as you said increases the length which should but not always increase air speed and reduce turbulence which should get more air into the cylinders. why do you think that they are said to increase lower end torque debatable or not ultimately the spacer is a debatable add on but a cheap experiment. agreed. -- if at first you dont succeed youre not cut out for skydiving .

on 19 oct 2004 234601 gmt joe avoidingspam@nospam.com wrote youre right - i shouldve said sensitivity in db. got subs on the mind... sorry for the misinfo. regards joe azwiley1 azwiley1@scpoaxm.net wrote in great info right up to you mentioned spl. spl is used only in subs and relates to how much air it is/can move. the number/measurement you should have referenced is the efficiency rating of a speaker. iamgoode@aol.com iamgoode wrote in looking to replace my spekers and want to get something to match the factory infinity amps. can some one tell me the rms/peak watt ratings input apreciated. sean rec.bicycles.marketplace the factory infinify amp is nothing special - its about 15-20 watts rms per channel if that the peak power rating is 40 watts per channel as specified in the dodge literature. most decent aftermarket head units are more powerful. one thing to note the front speakers are component speakers in that they use a crossover to separate highs from lows. youll need a separate woofer/tweeter combination to replace them. if youre just replacing speakers and leaving everything else alone you wont need the crossover itself as thats built into the factory wiring. also due to the relatively low power of the infinity amp youll want to get the most efficient speakers you can find. a spl sound pressure level of 92 or higher would be good. regards joe dont know how i missed this thread a while back. if you guys are still around are either of you bubbleheads .

cmon maxy.........lets play some more.........im just getting warmed up. hehehehe maybe ill track you down and run your ass over with my big bad dodge........if it can make that far. yeah.......thats right im gonna track you down you wuss. .

--webtv-mail-28252-5441 content-type text/plain; charset=us-ascii content-transfer-encoding 7bit well it looks like geekboy doesnt now what he is taking about and doesnt know much about trucks in general. he uses big words that he must have read in a dodge owners magazine and now all of the sudden he thinks hes a mechanical genious. i have owned trucks from the big 3 dodge ford and chevy.... my opinion the chevy trucks are the best all around yes i admit that the styling is getting a littledated but i still think they have the other two beat. ford i have nothing aginst but my opinion if you are gonna buy a big truck look a like just buy the f-250 and have it over with i like the new ford body style better than the last feminine looking 1997 to 2004 trucks. but thats not saying much. but as far as fuel economy goes the bulky ford is nick n tuck with the dodge. chevy= better performance fuel economy and bang for your buck in my opinion. i have a hemi and its claim of 345 hp....is a joke.....i bet if you put it on a dyno it wouldnt hit 150 hp. poor fuel economy with sucky performance.. i think the dodge designers need to go back to school. --webtv-mail-28252-5441 content-description signature content-disposition inline content-type text/html; charset=us-ascii content-transfer-encoding 7bit html body bgcolor=blacktext=white p align=center embed img src=http//www.angelfire.com/rock/cooper/skyline.gif /body /html --webtv-mail-28252-5441-- .
