Doesn't appear to be the MAF
Thanks to alll who have suggested my probems may be MAF related. I removed the MAF but the car would not run. It started and ran for about a minute, but then quit and hasn't started agin. I installed a known good MAF - thanks Steve for the loaner - and it still wouldn't start.
Where should I look next?
Here are my other posts for reference:
From 2/2/06
I took the 86.5 out for a spin this evening as I am getting ready to put it up for auction on ebay and as I was returning home it began to run really rough. I feathered the accelerator a bit to keep the revs steady but it was obvious that something wasn't right. The motor acts like it's not getting enough gas... wouldn't rev above 3,000 rpm... but did get me back home. (Approximately 2 miles from the first sign of distress.)
In the driveway the car would run ... but very rough... wouldn't go over 2,000 rpm without very slow pressure on the accelerator. At 2,000 it would bog down and then quit if I pressed the accelerator quickly, but with very slow pressure I could get it up to 3,000 rpm. There was no smoke, no odor of unburned gas, oil pressure held steady at 5 bar, and the water temp was normal. The car was last tuned in 11/05 and compression in all cylinders was within 5% of spec. I have been running the car on very little fuel as I am trying to sell it. The last potential buyers drove the car for about 10 miles and reported absolutely no problems.
As of now - about 2 hours after I limped back home - the car will start but it's obviously in some sort of distress. Again - it does not want to rev, but there is no smoke or unfamiliar smells from the exhaust.
From 2/5/06
I pulled the MAF on Sunday. The car started and ran for about a minute. When I tried to feed it a little fuel it quit and would not restart. I will reinstall the MAF and see if wiggling the plug changes anything. Does anybody have any suggestions where I should look next?
Thanks,
Jerome

I'll give that a try this weekend... if it's not snowing!
