Yesterday I went out and purchased a new ignition module that goes under the distributor cap thinking it may resolve my problem but still have the problem. It did seem to get a little better because now it will at at least plain out and hit 3400 rpm as to before it only got up to 2600rpm. I also purchased a new coil that goes under the distributor cap and will replace that soon. I am going to pull the fuel pump out sometime next week and make sure there are no leaks and replace all the orings. I don't have a live data scanner. Just a code reader but no codes come up.

Hey, thread went dead. Did you end up solving this, sounds exact same as what I’m dealing with?
