Diagnostic Help
After running my car really hard last night it threw like 6 codes. I thought it might have just been acting weird for no reason. I cleared them and drove it today and it pulled three codes and ran a little odd.
The codes that came up are:
P0134
P0154
P0418.
What would cause these to all the sudden come up?

p134 & p154 HO2S Circuit Insufficient Activity
p418 Secondary Air Injection (AIR) Pump Relay Control Circuit
Sounds like something caused a voltage drop. Did you almost stall the call at a shift point??
Anything else weird??

No, it just acts weird when it's idling and smells like gas. Might be an exhaust leak. Think that could cause it?

I don't think it is a leak codes relate to circuits not high/low readings. Check it see if any wires came loose or leaned up against exhaust and burnt through the wire insulation.
Maybe as u were driving hard one fell against something hot.
Are the codes current or history?

The codes were current. The wires weren't burnt at all but I ziptied them away from the headers anyway and tightened up one of the 02 sensors and it seems to have fixed it. Who knows, maybe it will come back.
