Car running lean. Need help!
Ok guys, I need some serious help! My fiancé’s 08’ EVO X is running lean and pulling timing and I just can’t figure it out. It has an AMS intake, Greddy exhaust, AMS down pipe, AMS mail in flash, AEM wideband, AMS front mount, and AMS intercooler pipes. It ran fine three weeks ago, the only thing that happened was that I went off track at a road course in Illinois. It pulled on some of the hangers and flanges on the exhaust. I have checked the fuel pump relay which I believe my dealership had already changed, but I changed it anyway, but it still had the same problems. I boost and exhaust leak tested it, the vacuum hose between the intake manifold and fuel pressure regulator is connected and zip tied and all the vacuum hoses for the throttle body are connected. Any ideas?
