Thanks guys for your time and wisdom.

I too thought about the timing seeing that it was the only thing that could cause the fire to happen in the headers. It was too far retarded so I advanced it.

We drove the car down to Fredricksburg this weekend and it ran much better. I stil think it needs more timing since it never pinged and it didnt have as much response as it has had in the past. So I will do that and let you know.

Terry...yes I can get the data from the Autoprom. I took out fuel from the VE tables, adjusted the idle rpm up a tad and it certainly delivered about 30% better fuel economy. So I think with a few more adjustments it should be real close. As soon as I know the timing is right I will record the data and send it too you.

Again, thanks for the assistance. I truly appreciate this website and your expertise!
