Well, I have an 86 ranger, 2.9l 5spd manual. got it for free, dropped a donor tranny into it, replaced the plugs, wires, and o2 sensor. It failed smog at idle. IAC is working fine, but... I have a feeling my issue is with the MAP sensor. Now, before I go spend another 40 dollars I dont need to, I tested it. According to the info I can find online, at idle output voltage should be 1.5 to 2.1V My output voltage is 3.5V. At 4k the output voltage is 2.3 volts. Am I reading the info I find online wrong, or is my sensor just polish reading vacuum backwards. It would make sense that I am running rich at idle if the output voltage is telling the computer to dump fuel when it shouldn't. Anyway help is GREATLY appreciated. Thanks
I tried posting on my local 4wd forum, but since I dont own a jeep(heep) I couldn't get any help on there.
