Help with engine codes I have a 96z28 and I just had the ses codes checked. The codes are:
p0161-O2 sensor bank 2 sensor 2
P0400-egr fault
P0300-random cylinder misfires.
Could the O2 sensor it's showing as defective be the cause of the other 2 codes? I just replaced all plugs and wires and can't hear or see a vacuum leak so any input from experience would be much appreciated

Not likely the cause of the EGR fault, but a possibility for the misfire. One question would be if the codes were cleared after you had the last work done. The misfire code could be from the plug/wires you had on there before. Maybe you should clear them and see what comes back. If you don't have your own way to scan the car, you should.

bank 2 sensor 2 is for cat efficieny, so it won't throw the other 2 codes.
Check your wiring make sure none of them are arcing anywhere and that they are wired properly and secured nice and good. EGR fault could be a clogged EGR or something, so checking out the tubing could clear that code.

ok thanks ill check that tommorow. another question about the egr, would it be worth it to delete it? what are the pros/cons of it?
