On mine, when I first bought it, the CEL light wold come on occasionally. It was throwing a code for the EGR. It would be on for a few days then it wold go out on its own. After a few months, it went out and hasn't come back on since.

Topher, what all is involved in that? Clean out the TB and MAF wires and maybe a new filter element? Anything else? I'm a noob at 4 bangers and OBDII.
