It's been a while since I posted, but here lately I came across a problem. I am not too sure how to describe it, but I'll try my best.

Before I begin, this only happens when I am in over drive. Not really noticeable in "drive"

When I am going up hills, with the pedal half way down, the car kind of "jerks" like it's missing or something. Kind of like it's losing power.It doesn't really do it on flat roads or going down hill. (Not that I noticed at least.)

And another thing I noticed, when I take off to pass someone, the car kind of starts out "rough" feeling with a small "jerk" but becomes fine right after.

Is this a sign of something bad? I never experienced a tranny slipping, but had one go out on one of my old cars. Not fun.

Any ideas? I was hoping something simple as bad plug/wire. Clogged fuel pump?

 

Sounds to me like your motor is starving for fuel. I would start by doing a fuel pressure check. If it shows that your pressure is low, you will need to look into a new fuel pump or FPR. Good luck

 

Thanks for the info. Ill get that checked asap. I was afraid it was something like the motor dying or tranny going bad.

 

You should always start these types of posts with Year and motor/tranny. Some cars have common issues it will also tell us what computer system we are talking about. When you compair a 93 with 02 they are almost completely different systems.

What you describe sounds like a what we call a stumble (engine related). But depending on the year and tranny it could have something to do with the torque converter clutch not disengaging smothly, Of course if it is a stick you do not a torque converter.

 

97, 3.8L, automatic

 

If its the torque converter switch how much would that cost to fix?

 

how long has it been sense youve changed the spark plugs and how old are the plug wires? have you had a ses light?

 

Actually haven't changed it yet, had it for almost 4 months. I had it planned to change them. No ses light. Ill change them amd see if that helps.

 

If you are not sure if the wires are less then 6 years old change them also.
