I have a 2004 Chevy Tahoe. The check engine light came on

Customer Question

I have a 2004 Chevy Tahoe. The check engine light came on a couple of days ago. I read that it may be because the gas cap was not on tightly. I checked. It was on just fine. Then I stated to think maybe it was because the fuel was so low. I added about $35.00 of gas and the check engine light went off. I was so excited that it was gone. And came back on today. I still have plenty of fuel. Any ideas what may be causing this?

if the engine light is on..there are code/codes stored in the will need to scan the computer with an obd2 scanner to get the codes..if you don't have a scanner,auto zone and most parts stores will scan it and give you the codes for free..these codes will give a clue to the problem
