ran it for a bit today and it finally showed a code. p0102, which is low voltage from the MAF. going to try and see what I can read on that one, other than just buying a new one and hope it fixes it.

I went back and forth in the yard a little stopping and going and noticed the pedal was a little erratic. it press real easy sometimes, sometimes it wouldn't. if I pumped them a lot it would return like normal, and sometimes not.... and of course the slow return was still there. I tried adjusting the rod nut on the pedal but no change.

the booster is new... but from about 8-10 years ago. it sat for a while and rusted up. when I pulled it off last year I just repainted it and bought another master cylinder. so who knows, maybe the booster is leaking on the inside

I did unhook the vac hose on the booster while it was running and started stumbling and wanted to turn off... so I just hooked it back up
