Bump! Any ideas?

Did some research and found a few possible issues to the EML+DSC+BRAKE lights:

1. ICV
2. Throttle Body
3. Throttle Harness
4. Speed Sensor
5. ABS/ABS sensor

There were some other suggestions about the wheel sensor?? and I noticed, while driving today that my wheel was off-center. Again the p1500 code alluded to the ICV being stuck open. Any additional thoughts?

Yeah, I read posts that said they either changed the ICV or cleaned it, but the problem came back. So I am back to square one!

We sure are. Let's see if we can figure this out!

OK. So I waited a couple of days before I posted this and I hope I did not jinx myself. Thursday night I decided to look under the hood to see if anything was out of the ordinary. I noticed the cover at the very front of the hood and just above the grill (please bare with me as I don't know the parts by name) that goes into what I assume the MAF?? was not put on correctly. Leaving a small gap for more air to pass through. I corrected this not thinking it would affect anything, but must say that after 2 days of driving no EML+DSC+BRAKE lights. SES light returned, but checked the codes - no p1500, just my typical "lean fuel" codes. I will post if everything changes.

lilbimmer: I hope you have solved your problem, but it seems implausible that that was the issue. The MAF measures air after it has been filtered. Any extra air till the filter is not likely to affect MAF readings. Any experts: correct me if I am wrong?

You are probably right! I know I had to use quite a bit of effort to put it on correctly so I don't know if I "jiggled" anything back into place. Will post if the code or lights come back, hopefully it doesn't.
