Rich, This is one reason I have always said to get the electrical system up to date with new parts: Alternators, Coils wires and so on. Then a lot of problems will go away or you won't even know you were going to have them. Weak fire under pressure ='s nothing, meaning not enough spark to ignite the fuel.

The car still starts far easier than it did before but now, again, it runs terribly. Symptoms are exactly the same: After 1/2 pedal, the tach jumps all over the dial, the car bucks and farts and nearly tosses me out of the seat. I lose acceleration until I back off of the pedal. All I know for sure is this: -SOMETIMES- the car runs better when the engine is cool. It has psych'ed me out 4 times in the last few weeks, thinking that I'd found the problem. As soon as I get hung up in any kind of traffic where I get enough heat to run the cooling fans, the engine goes to hell until it sits overnight or gets very cool again. Dave T. still knows his stuff, but the ignition didn't seem to be the problem. I have a nice white spark now. This one's just going to have to wait until Saturday at the Social.
