Is my motor toast?

[TheMajesticking]

I have a bit of a problem. When I push the gas halfway down. My car hesistates a bit like I am tapping the pedal. I don't know what it is. It started about two days ago. Today I ran a fuel system cleaner and changed my oil (mobil 1 of course). It is still doing it. Not as bad. I notice it more when my car is cool or has been sitting for a while. It doesn't do it at full throttle. Help me out fam!!!

When did you change your spark plugs. Sounds like your problem might be ignition related.

does it go away after a while? does it do it in gear? does it do it in park? when was the last time the fuel filter was changed?

hesitates or sputters?

if hesitates - possible combustion or ignition problem

if sputters - possible distributor problem.

Damn. Thanks guys. I haven't changed my fuel filter since i've had the car, or the plugs. I guess it sputters(whatever that means). I seems to go away as I drive, but only does it when giving little gas.

[TheMajesticking]

OH. My tranny fluid was kind of dirty. Could that be a thought?

[Deuce]

when it does it, do you hear sputters coming from the engine and/or tailpipe?

[TheMajesticking]

No. Just hesitation. Like bursts of power. I will hold it steady but it will go vroom vroom vroom. I have no clue. Not loud or anything. You get the idea.

What did you do to it 2 days ago that make it start? Anything stupid... like race?

Just let it sit for a few hours at idle.

It's your ignition... Check your spark wires.

I had the same problem, I bought and installed a new fuel filter, nothing. Afterwrds, I did a bit more tests and it came down to either spraks or wires. The spraks were dry and tan so it had to be the wires. Went down to local pep boys got wires and spraks for like $65. the car runs like a kitten..

...What happend to me is the car stumbled when I put a load on it. The only way i could make it up hill was to down shift into 2nd and keep the revs up. Mejestick I assume the car only does this when its in gear/drive?

definitely sparkplug related - if changing the wires doesn't work, get a diagnostic and rule out your distributor cap/coil.

I just drove it. I seems to only do it in 1st or 2nd gear. It has never done it in 3rd or 4th.
