Hey guys, so go figure after saying that my car is reliable, I am now leaning out under load. All I did the other day was take my battery out so I could put it in someone else' car and now it runs pretty poorly. At idle and light throttle the car runs just as it always has, slightly rich. When under load it leans out and goes off the gauge completely. I am running an l28et with the stock electronics, intercooler/bov, 60mm tb, stock fpr, pallnet fuel rail, aftermarket fuel pump...
I am trying to diagnose is completely before I begin buying new parts because I am currently without a job and have no cash, literally.
Any thoughts would be greatly appreciated, and thanks in advance.
If I have left anything out that you might need info on to diagnose please feel free to ask.
