Hey guys, the CEL light comes on from time to time on the MSM and I can find nothing that causes it. It will come on and stay till I shut it off, then the next time I start it, it's off. Happend about 5 times in the 7 or 8 months I've had it. Haven't taken it back to dealer yet because I don't want them to keep it a week to tell me they can't get it to come back on, and all is working well... Anyone else have a problem like this with an MSM?
Gas cap? That is something that tends to fix its self after you refuel some times. Sort of a new car, so maybe you just dont tighten it enough? Other than that, there are some guys around here with Ob2 software that can see what has caused a light recently. Hopefully they will jump in.
I have an Autera that can read codes, I live in Valley Ranch, let me know if you want to come by and see what it is.

You can stop by an Autozone and they will pull the code for free. I agree with Majik about try and 'tighten' your gas cap a few clicks.
And if Autozone can't find a code, I've got a data logger you can borrow that will catch intermittent codes...
The only reason I didnt suggest Autozone, I was not sure if they will pull codes that arent currently pulling a code. It might get old codes, but I wasnt sure. I know some of these techno geeks would be able to tell the last puddle you ran over with their computers... :thumrigh:Quote:

Check the wiring for the intake temp sensor right there before the intake manifold. It's attached to the intake with this big metal octagon thingy... The sharp edge of the metal has a habit of cutting the insulation on the IAT sesnore wiring causing it to ground itself. Wrap that sucker with tape...
That's my guess!
Never happened with mine. Of course, I have other issues (hard to start about 5% of the time and idle dip).

Thanks guys. Gas cap "could" be the answer, as it seems it happens following a fill-up most often...
