I am at a loss, I can not for the life of me figure out what is wrong w/ my car.
I finished the rebuild and installed 550cc injectors. When I drove it, it bucked and carried on whenever I got on it. Thinking it was the mas, I switched to a 2g MAS, b/c they're supposed to work good w/ 550s. I installed that, and my car still did it.
My datalogger was showing whenever I would get on it, my car would boost fine but then randomly throw 30-40 counts of knock. I thought it was my plugs and wires, so I replaced them w/ Accel wires and NGK BPR7ES plugs. I also installed a brand new O2 sensor, since my old one was shot.
Today I got a chance to drive it for a short period of time, and my logger was giving no knock, but timing was erratic and my O2 was bouncing between .70v and .92v. I dont have any CELs, but my battery light is on, I have a brand new alternator and battery.
Could anyone give me some suggestions on what I am doing wrong, I need my car I dont have a spare car anymore and I am really starting to get depressed about this whole situation, I can always diagnose or figure out where the problem lies.
