Update from yesterday. I changed the MAP sensor. Truck is still hard starting but with some persistence got it fired up. It stumbled and died the first time but then fired and idle.

Cold it now idles about 800 rpm. When warm the idle creeps up to 1000 rpm. It now has a big loping idle but holds steady.The temperature gauge seems to work now but stays pretty cold (didn't replace the sender as I couldn't find it) Acceleration seems a little sluggish but overall the truck ran ok.

Also, what seemed like a strong starter now seems like it may be free-spinning and not engaging very well.

Its seems I need to test the starter and will do that this weekend when I can get the truck on stands. Also I plan to clean the IAC. Are there any other sensors or controllers I should check for the rough idle?

Thanks
