Check Engine Light Shuts Off
 
This is the second time this has happened on my 2012 Laredo. The check engine light has come and the first time I had it read and it was an eval error. I took it into the dealer and the light turned off in the service drive. They said no codes were stored and no DTC's were found. Light came on again for four days and didn't get it read, but I assume another evap error again. The dealer keeps flashing the PCM, which I feel is a way to get me out of there. Any ideas what I can do or say because I hate being blown off.

Loose fuel cap?

That is what I thought at first, but it doesn't happen after a recent fuel up and the only part that I can replicate is it happen every two thousand miles. No other things have been isolated.

What was the code the first time?

This is how mine started and I had the same answers from the dealer. They must all be reading from the same manual when you call/ talk to them.

Like mentioned, as soon as the light comes on , take it to any auto parts and have them read the code(it's free). My code ended up to be a P0304 a misfire in Cyl 4. After several more times the CEL light coming on and off randomly over the last few weeks the dealer decided to run a full diagnostics.

It went in Monday for a new Cyl head. I will be getting it back on Tuesday.
9 days by the time I get it back if nothing goes wrong in the process.
