Well a few days ago the Service Engine Light came on as I pulled out of the driveway, of course this was when I was on my way to a job interview 50 miles away. It felt like the truck ran pretty $hitty, but I thought the 25+kt cross/headwind wasnt helping. ;-)
It seems that it's running rich as it was smokey a little bit at low/no load when engine was fairly cold, and a bit of a "burp" dropping down to 1500rpm. I think it may be the MAP / MAF sensor
anyway, I took it to both advance & Autozone to have the code read and neither can. It was suggested the ECM / OBD has a bad fuse, but I can't find which in both my Haynes book and owners manual. One guy said it's often on the Cig lighter fuse, but that one's fine. Did a search and really didnt find a solution
oh, and of course it didn't replicate the problem when I was at AZ. Apparently after it's run for a bit the symptoms subside
Thoughts/input? my immediate concern is obviously is making sure OBD / ECM is functioning properly
I've had 60hr workweek, but hopefully will be able to get to this on sunday
thanks
