This problem just started. I took it out for a drive, I drove a few miles to a freinds and it did just fine. On the way home it started to stumble. So I changed the fuel filter thinking maybe it is clogged, not the case. Once I get past that stumbling point to runs fine (at higher RPMs). Any suggestions? Thanks Don

Do you have distributor or coil over plugs on your engine? I believe they changed to separate coils for each plugs around 95? If you have distributors on each bank I would check the inside for pitting on the rotor and cap. Have you checked if there are any codes? How is the idle?

How old are your spark plugs? Could be worthwhile to remove one and inspect. If you decide to change, buy non-resistor plugs, the ones specified in your owners manual.

In general, check all vacuum lines and connections. Check your alternator output. You should have at least 13,5V at idle with AC on. If not, your voltage regulator could be worn down. Very easy fix. What mileage are we talking about here?

Take a minute to complete your profile with car model and location, and the forum members can give more accurate help (hit User CP button top right of screen).

I want to thank everybody for there help. This is what I found "with your help".
I'm going to try and clean everything up and try it first. I will have to order new caps and rotors. The lowest cost I found were $125.00 per side.
