Let me draw it out a little better last post was from my phone and its a PITA to type on,
truck had an intermittent rough idle, While it was doing this i pulled both plugs on the passenger side VCH and it made no difference, I then found that the connector was melted from the glow plug wire that ran next to the #1 injector pin. So i then replaced the gasket and the UVCH, I ran a buzz test prior and showed #1 fault.. after i replaced the gasket and harness I ran another buzz test and still got the #1 fault but also showed all passenger side high to low fault.. which it didnt do before. At this point I had not replaced the outter plugs as they still looked good but both had the clips broke off.. so today i decided to replaced them thinking I might find a bad wire, at first i wires the 1, 3 plug injectors backwards. (the colors changed and i was in a hurry
) wen i tried to start it, it ran but obviously horribly, I found my mistake and corrected it..
but heres the weird part, when i started it after fixing, it still ran very rough. i let it run and i went under the hood and was able to unplug both passenger side harnesses and it made no difference, then like magic as i grabbed the rear one again it cleaned up the idle, then like magic again it as i grabbed it it cleaned up alittle more, i then pulled the rear plug and it made an obvious difference and then pulled the front and it made an obvious difference but still had the #1 miss, after that it ran just like it did before,,
so My question is for one, whats going on with my #1 injector and two is this a wire problem or an IDM problem.. i dont believe I did anything when i grabbed the wires the connections were solid and I even tried to make the reverse happen by pulling and slightly twisting the plugs and nothing.. basically it did the exact same thing it was doing when I bought it only I thought I fixed that with the harness simply because it hasnt done it since.. any ideas? thanks!
