backed in the driveway after work today...about to turn the car off and the rpm's dropped like mad...about 4-500, felt like she was gonna die...did ita couple times...i turned the a/c off, and it was fine so i figured it had something to do with that...just pulled in for the night and it did it again like 3-4 diff times while i sat in the garage! anybody know what it could be?

goin to work this morning...was in 4th and let off the gas and it sounded/felt like the car was sputtering...bad gas? fuel filter? still doing the rpm drops too when its at idle...

 

well got some gumout thinkin maybe it was the fuel filter/pump..then on the way back from my stang meet it started acting up again and the check engine light came on...WTF waiting for the motor to cool to take a look at a few tings...any suggestions?

 

Iagree with you. A fuel filter change would probably solve your problem.

 

me and my roomate cleaned out the throttle boddy and..damn cant think of the name of it off the top of my head...thing that bolts on the front of the plenum...well cleaned both and the check engine light went off and it runs better..but its still boggin down around 40mph in 4th when i let off the gas....

 

im his roomate...and he couldnt think of the IAC, thats what we cleaned i guess the next step is the fuel filter

 

IAC and fuel filter should be checked before even making this post...but goodluck fixing it...and sometimes the IAC needs replaced instead of cleaned, but letting off the gas wouldnt cause that, putting it in neutral while moving would though

 

I'm having the same problem with my car. It now starts, but then dies immediately, as if starving for fuel. I've done everything to my car, including the fuel filter. I think the problem could be a bad fuel pump.

 

changed fuel filter...added gumout and fuel injector cleaner and so far so good..we'll see what happens...as for checking that before the post...oh well tough i didnt do it cuz i didnt know what would cause that..isnt that what the forum is for? asking quesitons for things you dont know?
