Check the catalytic converter to see if it plugged by checking if exhaust flows freely out of the tailpipe when the engine is running.

Check that the plugs and wires are ok, and then go deeper by seeing if the coil packs (if equipped) are throwing any codes in the computer for a misfire condition.

Hope this helps!

Truck backfires and stalls when excellerated half way.


Sounds like the timing open the distributor and in there is a relector,is there alot of corrosion? This reluctor has a tendency to shift out of position causing the vehicle timing to retar,Another area to inspect is the MAP (manifold air pressure) .This sensor monitor engine load according to vacuum when this goes out you cant accelerate the vehicle and it sputters as the vehicle tries to accelerate,you need to check that the vacuum hose has not come off,or just failed

Engine surges up and down and dies repeatedly unless i elcellerate immediatly and continue to excellerate for a whil. most times then it will continue to run but not always. have already replaced plugs...


I'm sorry to hit you with this...but it sounds like your "PCM" powertrain control module...is getting cranky...and may need to be replaced soon...They can be quite pricey...but the car will not operate properly without it...Sometimes...when they start to go bad...the car will act up for a while....then...it will run good for a while....then act up again...but one day...it will go out completely...and when the car runs...the idle will go up and down out of control...start to spit and sputter...and then...won't start at all....My suggestion...get it diagnosed by an honest mechanic...You don't want the computer to go out on you on the road....word to the wise....GET IT DIAGNOSED>>>>ASAP>>>I hope this was helpful.....PEACE....

95 Eagle Talon stalls out after driving for a while. Has new ignition coil, plugs and wires, computer and fuel pump but I've been told it has something to do with the fuel line, any help?


I have the same year and stalls out occasionally in the beginning and now I can barely drive a quarter mile. All of the parts you listed I've tested and appear ok but what I'm thinking is not fuel because it would act crazy gasping for fuel but the camshaft and crankshaft sensors. If either of these are failing then the engine stops firing and dies. Also could be the alternator or battery. If not enough charge then the car could die. Mine dies like I turned the key off (and don't think it's ignition switch) and gauges all just drop to zero still sounds like engine is sort of on until I finally coast close to stopping and then dies and oil light comes on.
