I was adjusting the fuel pressure and I got it to where it should be, but it would studder at full throttle from idle, so I richened it up. So the first time, I was going down the street and I was full throttle, and I get a bang and the RPM's are shaking up and down and it studders. So I tweak the fuel pressure again and next, I go down the street and WOT is good but as I am turning around, it goes BANG, and knock knock knock. It doesnt start for 2 minutes straight, but I get it to start and limp it half a mile home. Anyone have any Idea's?

 

Is there a chance you might've overheated the engine and the ECM killed the fuel?
When I overheated mine the car just died and it sounded like piston slap, it wouldn't start until it cooled off. Scared the s#!t out of me, I thought I blew the engine.

 

Nope. Pretty sure it didn't over heat. It stayed at 160 the whole time.

 

Anyone have this problem before? I need to fix it asap.

 

Do you have any error codes, is the ECM still in limp mode?
Drive it again (or try to) and post what is going on.

 

Will do, I am going to turn the FP down and drive it around the block again.
