So I've tried searching google and the forums but my problem is kind of overly specific and tough to pin down without asking.

I have a 1993 SC400 that won't idle no matter temp
A little background,
the car was sitting for an unspecified amount of time (up to 3 years) and had some pretty bad gas in it. ran it about 50 miles before I realized how bad the gas was and completely drained the tank and replaced the fuel filter. before this to get it running I replaced the pump, strainer, and fuel pump ECU. This problem happened about 100 miles AFTER I drained the gas and replaced the fuel filter (I filled it with 93 octane some octane booster and lucas oil injector cleaner) I've cleaned the MAF and the IACV and replaced the PCV and it's still giving me issues. It's throwing codes 31 (maf) and 55 (Knock sensor)

Please ask away and I'll fill in any info I've forgotten

Thanks!

EDIT: If I unplug the evap hose from the pcv valve it will idle (poorly) if I unplug the MAF no change

Haha didn't even realize that just unscrewed it and hosed it down with MAF cleaner. Upon closer inspection I have to concur with you
