Default Electrical load and Revving car up=CEL

Alright, so I have a 90 GT and there are a couple weird things..

When I rev the car up or I get on it, the check engine light comes on. I have ran the codes with the KOEO test and all I get is 32.

Also, when I turn on the Air/Heater, the CEL comes on. Then when I turn it off the CEL turns off. My reading on the factory volt gauge is like 2 bars above 8.

I was seeing if anyone else has any problems like this? Thanks.

The codes I have are 41, 91, and 32.

Which that is sort of weird cause its saying that im running lean but, I have no o2's and it should be in open loop.

But thats all the codes I got.

Did you do the KOER test with the heater on?

Code 32 is for the EGR and that will trigger a CEL when the vehcile is running if theres an issue with that system.

Id start looking at some wiring diagrams to see if you have a short between wires for the heater and CEL issue....
