check to see if ur fuel pressure regulator is flowing in the right direction...seeing as you can change the fuel pressure, I would believe you have an aftermarket regulator. I had the same problem w/ a 300ZX Twin Turbo...the lines going to the aftermarket fuel pressure regulator was backwards.

 

i have never replaced the regulator before i wanna do the spool boy mod does anyone know where i can find a complete how-to

 

well im pretty sure i have a dohc atx comp in my 2001 2.4 turbo non ngc mtx. will this comp. cause me to not be able to go past 1/4 throttle without it runnin real bad??

i just dont know what else to check

 

you need a rrfpr and a map clamp.


sounds like the mixture is messed

 

i have a map clamp on it and what kind of rrfpr do i get just one from ebay and i bypass the stock regulator right? do i need a return line
