Something like that happened to me...

Started the car, ran good for 15 minutes. Then it started to sputter and died.

Redid all wiring, checked CAS timing like 10 times, checked cam timing, tried another CAS, another igniter, another set of coilpack, checked for spark and fuel... I even tested my wiring with an oscilloscope. Redid all ground too!!! Everything was good...

Then I decided to change the spark plug just because I was out of idea...

Put the new plugs in... started right up. I was soooo pissed that I loosed 3 freaking weeks of nice weather(that we don't have a lot in Quebec) because of stupid spark plugs!!!

It's not because it's doing spark in ambiant air, with no compression pressure, that it is still doing spark in the combustion chamber with pressure and Air and Fuel mixture!!!

It might not be the same thing as me, but I think it worth a try. In 10 years of as an automotive tech, it was the only time I saw that.

I hope it help,

Frank

EDIT : Damn, should have read your last post!!! Good think she fired up, have fun!
