Okay, I drove it around awhile, actually burried it over the front bumper in mud, back end sticking up in the air. Anyway heated it up good while being yanked out by a ford ranger. Turned it off let it set about 15min, and like clockwork the problem started. First I tried the wire jumper, it made no difference. So, I did an ohm check on the Afm here are the results. E2-Vs was 460ohm which is over the 20-400 range. E2-Vc was within range E2-Vb was with in range. Then E2-THA was 1617 ohm which was with the afm being warm to the touch, probably about 70deg. which is out of the range for that temp. Then I let it set for a bit longer and rechecked. Everything was the same again but E2-THA now I had nothing at all when I checked it.? Tried to drive it, started up fine, Idle was rough and it sputtered and bogged if you try to drive it. So what do I make of this ? Whent back out after truck was completely cold, and checked the range on E2-Vs, It was now at 615 ohms which is even further out of the 20-400 range. And was still getting nothing on the E2-THA pin. BUt the truck is running fine?
