how does this happen??
 

today i let my friend give me a ride in my car so that i could see what it feels like. he goes to get on it and it made no power in 1st and 2nd. right before the run it stalled around a corner and the idle was alittle jumpy. we pulled over and i thought the fuel pressure gauge said 0 so we went home and it was actually pinned around to over 100. i dont know why this happened. how can a afpr go bad? i just put this one on a few months ago. help the cars running like crap and the pressure wont go down.

yes, they can go bad. check to see if the vacuum line is filled with gas...

take care,
adam

Some fuel pressure regulators don't react well to alcohol or some other chemicals that may be in fuel injector cleaners or octane boost. I had a Paxton FPR that went bad because of some chemical I put in the fuel. I can't tell you specifically what it was, though.
