So my car has been throwing some codes P1133 for HO2S(whatever that means) and PO133 for O2 insuf. switching. Some are saying the MAF is dead and so is the O2 in the header. Well I logged it and the MAF is showing plenty of Hz's and the O2 has plenty of mV's although they're like the hills of San Fran.

Also, anyone see an intermittant working IC pump? I know it works at idle but not sure on WOT. After a short pull temps skyrocket up to 145* on a stage 2 pulley. Is there any way to tell if laminovas are damaged?

 

The Heater in the O2 is dead. I would replace it.

 

Ya I figured that was dead after driving through a river. I think the MAF is good as it still reads everything from idle up to redline Hz wise.
