Customers C5 came in with a bunch of codes, cant figure out problem Friend of mine has had several codes on his C5 for quite a while. The comes come on after driving for awhile, after clearing them the car goes back to running fine (runs mid 10's on nitrous). Then after driving for awhile they randomly come back.
PO135
PO141
PO154
PO155
PO161
This is a 98 C5 auto, heads/cam/everything/nitrous.
Any ideas what could be the problem?

HO2S Heater Circuit Bank 2 Sensor 2
damn that's gotta be every code in the book for the oxygen heater!!!
Is the Engine Sensor fuse blowing? Maybe one of the O2 wires dropped and is shorting? My car did that a month ago or so... once the headers got warm the wire would tap it just right, melt through and blow the fuse...
My car was also setting a MAF low voltage code ... but w/all those codes related to the heaters i'd check to see if there's any blown fuses...

Was this problem ever solved? I'm throwing a PO135, PO140, and PO155 as well. I did a search and found about 10 different threads where people had at least one or two of those codes showing, but nobody ever followed up with what their problem was once they got it fixed.
