86 caprice wagon serivce engine soon light and heater

When I turn the heat on in my caprice wagon I get a bad smell like oil or gas like and the service engine soon light comes on not sure why any help would be great thanks

Does it run any worse when this happens?

Does it do it on all temp settings including A/C or just when you switch to heat?

Nope doesnt run any worse but when the cars idling the heat slows down a lil when I accelerate it gets more power haven't tried it on ac but on vent heat and front it was the same

I'm wondering if it's an electrical problem with the blower motor. try unplugging the blower motor and see if it still sets off the check engine light.

Dan, check your PM's.

Dan scroll up to the top of the page. You will see a menu bar and on the right side, it will say something like "you have 1 new message".....click.

Did you pull your code from the computer? It would help to know what it is. Are there any other symptoms? Could you punctuate once in a while so that I know what is a single thought? It is difficult to read without the punctuation.

Thanks tom checked it. No I didn't j can't check the code cars to old don't have the tools. When car is idle heat gets lower and smells a little, when I accelerate gets higher smells a little also. I'm thinking it has to do with the heater core and definitely going to replace the coolant, and add cleaner coolant.

But you do have the tool. That's one nice thing about OBDI.



Checking codes with a paper clip.

Actually I'm going to flush the system out and try a new thermostat.
