Thanks for the replies,

I have ordered the pickup coil and should have it tomorrow. If it still does the same thing, I will begin to look for other possibilities.

I never considered a vacuum leak but I somehow doubt that this is the problem since it is almost like a switch being flipped. It instantly goes from running perfectly to really bad. I can just barely keep it running and sometimes it will quit all together. If I let it sit for just a couple of minutes, it starts and runs just fine for a minute or two then starts to buck, back fire, etc.

HI No computer chips in that car, only the MSD box.
