    Miss fire at # 5 cylinder only under load

    i chased this kind of thing around the ignition and fuel for a couple years once. intake gaskets fixed it. One clue would be the misbehaving cylinders spark plug getting ashed up from the oil its sucking in from the lifter valley. My oil consumption also reduced to a manageable level, mind you...

    4L80e weird 1-2 shift

    whats your speedo doing? I had this happening one time. The speedo would be reading zero until I was doing about 40km/h then it would go from zero to my speed instantly and shift from what felt like first into 3rd quite violently. new speed sensor on the transfercase fixed it.

    RedHead Steeering Gears.....

    I tried to tighten the input side adjustment, couldnt get it to budge with my couple macgyver moves to grip it. Did the top adjustment, made a big difference but waiting for a rag joint in the mail

    4l80e clicking/rattling noise

    hows the rubber trans mount? mine sounded like a u joint was going to come through the floor. When I figured out it wasn't I let it go for... longer than I care to admit.

    How to: Install DIC in gmt400 overhead console

    ITS VEEERKING!! so, tried another computor from some scrap truck I raided from the car dump on the rez I was working on last summer that I planned to turn into blackbear as a core. I honestly don't remember what the truck was. Must have had a 4l80 because it drives just fine. ALSO makes my DIC...

    How to: Install DIC in gmt400 overhead console

    I guess I can live without all the real neat stuff. I have a metric/on of unit as well. It uses less wiring that I already have in place, and im hoping I can piggyback the temp circuit to the trans sensor anyway

    How to: Install DIC in gmt400 overhead console

    Tried my original computor. Got another DIC. Put in a stereo that has SCV and it works, confirming VSS is actually working. Still the same stuff. I do notice my 2 dics read the temp 5' different. The first one said 22 and the second says 16c. Anyone want to try testing one of these units I got...

    How to: Install DIC in gmt400 overhead console

    Tried my original engine computor and another dic. Still the same result. I tossed in a stereo head with the SCV feature and it functions, so the VSS circuit seems functional. I must have crossed up the class 2 wire. I hooked it to a rather large purple wire. Scan tool still functions as well.

    Like kenny brought up, start with the basics. Could be contaminated fuel

    7.4L to 8.1 Swap?

    Theres lots of ski boats and small/medium cudi cruisers came with the 8.1. Might have forged pistons and cranks in them too. Never took any apart myself but played around with some back in my old summer job in college. Seemed like a good plant

    Can a C3500 5.7L 4.10 beat 10 MPG?

    mines 96 k2500 5.7 auto with 3.73. I got 10 in town for years. It was closer to 12 until I got some new tires that where noticeably heavier than the old worn out ones. Many years later I bought a good size camper and couldn't do over about 90 with a tailwind on the prairie bringing it home and...

    I just took a load like that through the canadian rockies with my 96 8600 k2500. 350 with a blackbear computor set to stage 1 trans tuning(which I regret should have kept stock or maybe ill send it in to try stage 2). I dont have a trans temp gauge but I had no issues. It was hot as balls the...

    How does the behingd the seat jack cover mount?

    the threaded rod on mine is threaded into a welded on nut that is part of the floor and sticks out under the cab exposed to the weather. I managed to get it out once without wrecking it but it took some doin. When my jack failed and I went looking for another one like mine with the planetary...
