Ok so my MAF went bad. Car ran lean for a bit. Replaced MAF. Car smelled so rich I thought someone was just pouring gas out my tailpipe, and then it leveled off and went to normal. Idle is ridiculously quiet now too (I have a 3 inch exhaust and I can't hear it idle anymore). But anyway, this morning on my way to work, the car would not build past 10 psi and acceleration under half throttle was super jerky, like when you run an MBC (which I'm not anymore) and then I got thrown into hard limp mode and it won't build past 1 psi. Anyone got any troubleshooting ideas for me to try?
