I think I'm running pretty lean and is anyone else having/had an issue like this? I even saw values as high as -40 and while cruising I was running at -10 to -25 and misfires are aplenty when this happens, along with knock upon accelerating again. It has also got P0101 and P0171 set

Both are MAF related codes (p0171 is also vacuum leak related thought), so you could try unplugging it and see how the car reacts, just don't go WOT with the MAF unplugged.

Im running a constant -7 to -10. Was pretty much -10 to -12 before I fixed a few exhaust leaks. It always locks in at 0 at wot thats what confuses me though...

I go about -2ish at wot and I might have another MAF around so I'll try that one and unplugging it

So I unplugged it and It stalled, I smelled some gas and it also wouldn't let me go anywhere, it said reduced engine power, but I plugged it in and it ran fine. But at WOT I run about -8
