On both banks?

 

^ Wondering the same myself...


I had a problem with a both banks too rich code that was cause from my stock fuel pressure regulator going out. Was allowing fuel into the intake manifold through the vaccum source line.

System too lean code... Stupid phone

 

You are still running a MAF correct? If so start checking for intake leaks between the MAF and the intake ports. Make sure the MAF housing is not cracked. How is your idle speed?

 

truck idles pretty good. I hooked my compressor up to the manifold today and all I hear is a sound like the intake is filling up with air. It doesnt sound like a leak tough. I am gonna swap mafs with a buddy of mine tues to rule that out. The truck has been doing this for about a year, just now getting around to getting it fixed as I never drive the truck.

 

How is your pcv routed?

 

Filters on both valve covers, that's all..
