Tune was just working... Now runs rich
Hey guys.. I have a 93 gt2860rs on very low boost stock injectors on MSPNP. Boost gauge reads about 8 psi. Tune was fine and afr was just fine... Now it shows that I idle at 9.7-10.1. Driving shows 13.5-14.5. Once I get into boost afr shows 12-12.7... But at the same time it jerks or sounds like it miss fires... So I re calibrated my lc-1 and still shows it running rich... What else should I check for?
I was getting ready to upgrade my whole fuel system until this came about...
