SO we found out (thanks to Idget) that i was missing a restrictor pill in my 02 WRX. My question is could that be causing a lean on bank 1 code? p0171?
Nope, the pill is there so you can hit target boost with a bleed system. List of mods?? Lean on bank 1 is usually a fuel trim code, so if your fuel trims are too lean for a intake or something like that. Russ
Without the restrictor pill the car is hitting limp boost at 9 psi. So until he gets that little pill, no.
If you're getting a lean on bank 1 code, the last thing you want to do is turn up the boost. Get somebody who knows what they're doing to hook a computer up to your car and figure out exactly what's happening.
The first thing I would check for is a massive pre-turbo/post-MAF intake leak (assuming the stock airbox).
Thanks lee.... yea stock airbox.... i pretty much drowned my car in soapy water lookin for boost leaks and i found nothing.... As for having someone with more knowledge look at it..... I live in rochester and havent found anyone willing to help. So if there are anytakers, i am willing to pay.
Check everything when we pulled the intercooler off. Then double checked when we put it back together... it also has a bad hesitation at like 4500rpms.
