My check engine light comes on when I turn the key like normal. But nothing I do gets me a code and im worried. Because of my idle problem..

I disconnected the MAF, air box sensor TPS and IAC.

I accidently ran with cylinder 3 and 5 wires swapped for a few secconds no light.

I also ran with one spark plug wire off. No light..

 

I know you have a DI but without the year in your sig it makes it hard for people to help you.

It takes more than a few min of something being wrong to set off the CEL.

No light no codes.

 

Hmm I wasn't aware.

Fixed my signature for you.

 

LOL!!!
Thank you!!!
