Wow lol you threw all those parts at it as a guess ?

Is the check engine light coming on or flashing?

Have you cleaned the maf?

Checked fuel pressure?

How does the air cleaner look?

At what point does acceleration start to stumble? Is it for the duration or when it hits a certain rpm.

With all the stuff you changed you may as well check fuel pressure, and replace the fuel filter.

clean the MAF no CE light starting stumbleing on accelertion havent check the Fuel pressure or change the filter

It could be a bad pickup in the distributor also, there known to go bad. Most times its much easier to just replace the dizzy because you need to tear the dizzy completely down to change the pip

All you need to take it apart is a roll pin punch and a hammer. Not too hard. It's an extra 10 minutes of labor VS an extra $300 ~

If you're mechanically inclined, rebuild your dizzy. If you have cash, get an MSD offering. Then check your timing.

Had a 94 Cougar with the same issue and it was a bad MAF sensor.
