I think that intermittent fuel loss from the pprv was causing the already hot running cylinders to really spike in heat because of sudden lean conditions.

thanks for all the help from everyone i figured out the problem, the whole goes, i bought the car with a miss fire, i took the chance with my experiences with motors knowing it was either igniton or fueling, so the car had a few issues...bad battery, alternator cable eyelit connector broken, bad cylinder3 cop and fprs bad as well. pulled the plugs found cylinders 5 and 8 spark plugs were blistering and the gounding bridge were melting closed, figured, replaced all and drove her around normally just fine until i went wot and going into shifts would stumble, did research and found out about this pprv valve, removed bought a 30 dollar submersible 5/16 hose and clamps, she runs flawlwss now. they way she should, just gotta double pump before a start. im happy with that.

If you don't have a wideband get the A/F checked. Just because it's running good doesn't mean it still isn't lean.

I ran a PLX for years with no issues. I'm currently running Zeitronix. A couple friends are running Autometer. I think Innovate is a popular one on here.
