Well today I went thru and ripped apart my UIM. Replacing my PCV valve and fuel pressure regulator. Checked the plugs & cleaned em; cleaned the UIM, TB, and MAF. Also cleaned my K&N filter. Started her up and the CEL was gone, she is running much happier. Thank you all for your plethora of information.  x 10E600

Yeah, right!
That is why we frequently tell posters to WRITE DOWN THE EXACT CODES and then post them here to receive CORRECT advice.

Correction it was not the map, it was the MAF, I had 2 weeks off and hadn't done the codes, sorry  i'll be more careful and double check. At least i did check to be correct, some people dont. Sorry for [censored] info.

In any event, the MAF sensor is not the usual problem on these engines....
