Ok I just threw my first CEL code ever on my JB 20th. She is just shy of 75k mileage wise, her modes are full 42dd 3inch street exhaust along with neuspeed Pflow intake.
Just read the CEL and its only throwing P0172
P0172 - System Too Rich, Bank 1
Excessive fuel pressure
Leaking or contaminated fuel injectors
Leaking fuel pressure regulator
Low fuel pressure or running out of fuel
Vapor recovery system
Air leaks after the MAF
Improper seated engine oil dipstick
Stuck EGR valve
Exhaust leaks before or near HO2Ss.
Any of you guys have some insight on how I should tackle this little prob.
