Check Engine and heat seater - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So my Camaro has the check engine light on for the O2 sensors, which I attribute to the cam, tune, and custom headers/exhaust. The light used to always be on.

Lately it will stay off for a few days, then come back on for a few days, and it's been cycling for a few weeks now.

It got pretty cold here (Florida) a few days so I like to use my seat heater. The strange part is, when the CEL isn't on, the driver seat heater doesn't work. When the CEL is on, it works no problem. The passenger always works.

Any thoughts?

Try driving from the passenger seat when the cel isnt on....j/k...it's probably coincidental with the seat and cel..tune the rear o2's out and with it, the cel....

I have a similar problem. My seat heater has been spotty and my CEL comes and goes. I'll see if I can correlate it.

FYI, my CEL comes on because my misfire detection limits are off in my tune. I need to tweak them for sea level.

Well my CEL stopped coming on. I haven't tried seat heaters since it has been crazy hot. I'm just going to take it as my car hates the cold.
