Well you'll spend more money guessing blindly in the dark than you will paying someone to read the codes. I'm not sure I understand your resistance to this. Possibly you can get someplace like Autozone read the code for free for you.
If the light went out briefly when you fiddled with the cap, you might have a vacuum leak or other problem with the evaporative emissions system. The code would tell you this.

I forgot about AutoZone thank you for reminding me I will do that, husband thinks I need a new gas cap so if the codes say there is a emission vacuum leak then we don't have to replace the cap. Thank you kindly.

well iv had that problem with mine before and it was the the number 1 plug wire but it could be anything. like an O2 sensor. what i did was when i came on took it to autozone or any parts store like that and had them hook up the code reader to it and that would give you a pretty good area to look at and best of all its free. you just have to make sure the light is on when you take it.

Yeah, I plan on doing the AutoZone thing as soon as the light comes back on again. Thank you for the input.

How much would an air cond condensor cost? I hit a deer in Nov and the antler went through the air condensor and I have no air. Any answers will be helpful.

Online parts suppliers are selling the Tahoe condensers for around $225.00.

Take it to AutoZone or other parts store where they will read the codes for you to find out why the SES light is on.

I hope you had the condensor lines capped off to prevent the rest of the system from becoming contaminated.  Otherwise other components may be damaged.

Nope didn't know that. Maybe that's why the service engine light comes on. Wow thank you.
