I agree. I suggested earlier to check the cap and the wires.

I had the misfiring and tach jumping problem under acceleration for a long time. Checked and tested everything. Finally took some electronic cleaner and sprayed connections of ICM and distributor windings. Corrosion - green color . Darn it if it didnt stop it dead in its track! Still cant believe how simple a solution. Just something to know if it helps anybody.

Yep, it's been mentioned here many times over the years, but definitely worthwhile repeating, that it's sometimes just a poor connection with the short wiring harness between the ICM and the ignition coil that can cause an issue.

Cliff,
verify there are no issues with the MAP sensor vacuum line. This is my new solution to everyone's low power issue cause it worked for me (I just posted about it). Certainly can't hurt to check it out.

Replaced the spark plug wires today and all problems have disappeared. No more stuttering, sputtering, or tach jumping.

The three front wires were okay (1, 3 and 5), but the three back wires (2, 4 and 6) were in terrible shape and almost crumbled in my hands.

Also check your spark plug leads for cracks, etc. I had a similar problem on an old ford 6 cylinder once. A buddy told me to check the wires in the dark with the engine running. I did and saw a couple of wire arcing .



Cliff, I hate to mention it but I told you so.. ;-)

So basically the car needs an old-fashioned tune-up? I'd replace the other usual while you're in the mood (fuel filter, air filter, PCV valve, etc.) and order a spare coil and ignition module if you don't have them already.

Well, yeah. 😁
