its either your coil pack or power transistor. Double check your transistor sometimes they come loose.

Had the same problem a few year back and ended up being the p. Trasistor being loose just like 2gfwd said...

This will help you test the transistor. If it checks out good, it's going to be the coil.

Check at Autozone or Advanced Auto Parts, they usually go for $120 there.

You're sure you didn't put the plug wires in wrong? They are numbered on the pack so I'd check that too, I've been dumb enough to plug them in wrong and denied to hell and back that they were wrong and went through checking everything else before swallowing my pride and seeing that I didn't put them in correctly.

Know anybody in your area parting out a 1g dsm? Craigslist is my best friend. A lot of guys on there have saved me a lot of money
