Help with running lean. Freshly rebuilt lsj, ingen cai. Zzp stock pipe with wideband installed. New fuel pump, new sensors, new injectors, new fuel rail. New air filter. Afr gage is pegged at lean. Runs in the green at initial startup, 40 seconds in it leans out. I did not replace PCV VALVE. I have gone through all vacuum scenarios including pulling sc and intake and regasketting. Did overlook pcv again.

Cylinders 1,2,3,4
after 6 miles.

 

What pulley, injectors, and tune are you running?

 

All factory, just the pipe and cold air intake.

 

Car sat for 5 years with spun rod,seized up. Oil pump failure.

 

Stock tune from what I'm told.
