Checked fuel pressure its fine. 57-58psi
No broken valve springs.
Brand new plugs installed today before the log.
Wires are 3 months old.
I had the car running nearly perfect with no backfiring or popping, i sent it to the body shop to repair the damages from an accident and the car has been doing this since the day i picked it up from them.
I've heard that it could be my glasspacks have came apart and are causing a restriction? any opinions on this? Its the first time ive heard of something like that. Thanks to anyone who can help!
