Re: 3.0 runs rich with idle problem
I have the exact same issue, running rich on both banks, but don't believe its from a vacuum leak. I haven't found one yet using propane. I was wondering if you might know what the specs, (voltage/amperage) should be on the MAFS at idle. I have a constant .001 at idle, and at 2500rpm it only goes to around .04. I don't know squat about these things and just learning how to use my OBD 2 scanner along with my manual. Just an old man trying to do it himself and save some $. People try to take advantage of us elderly at times if they sense we don't have a clue about what a code is. Mine started with a P0172 and then P0175 and the shop I took it to tried to sell me a new fuel pump and PCM. The BASTARDS!!! I'm now determined, with help and advice, to diagnose and correct this myself. Learning a few new things along the way as well. Any suggestions would be appreciated. 1st time on this site and hope I posted this in the correct spot. My 3.0 is the FFV. Not sure if this makes any difference or not. Thank You!!!
