    Voltmeter Bounce

    https://imgur.com/gallery/UAy1550 I’d be willing to bet my bounce was slightly worse than anyone’s haha. Anyways, good grounds, good flasher, and a new gauge fixed mine. It still bounces a tiny bit but not bad.

    XJ Steering Shaft Upgrade (88-94 Trucks) 95+instructions on page 31

    I just "completed" this mod. Sorry if this is a repeat comment, i didn't want to read thru 47 pages to see if someone had incompatibility like me. BEWARE - i got my steering shaft off a 1999 Jeep Cherokee. I was thinking the later the year the less rust - being in the Midwest and all. The...

    700R4 downshifts from OD to D on highway

    Playingwithtbi Can you go into more detail on how to view these settings and change them if possible. I have the necessary cable and software that you have screen shots of above. My truck TCC goes in and out depending on the weather at about 75 on the highway and I’d like to adjust the settings...

    The Stupid Lift Questions Thread

    I second this. I want to put a small body lift (maybe 3") and new gears into my truck. It just so happens that 315/70/17 and 3.73 gears balance each other and i wont have to mess with the speedo gear. :) What are the tire size limits of cranking the keys and what are the limits of a mild 3" body...

    CEL triggers only while cruising

    Have you run into this problem or has someone else? I think the intake vacuum alone should be within the control window of the ECM to compensate for small changes in back-pressure.

    Mine was tucked into the wiring harness shield thingy and cut short with no connector or anything. I attached it to the intake manifold ground near the temp sensor.

    Is there something you would recommend? It’s true dual setup.

    SOLVED!!! Yup that did it. Oxygen sensor is reading great now. Only issue now is i'm getting some spark knock - but its probably just from fuel trims that are way out of wack. I hope the computer will work it out soon! Moral of the story: Get an exact service manual for your truck Check...

    CEL triggers only while cruising

    I verified my voltage measurements with another DVM and its accurate. See attached images for resistance. I re-checked the procedure of jumping the O2 harness to ground and starting and reading the voltage the scan data shows, no surprise, ~0.45v. It shows 0.4 to 0.5v almost all the time. I...

    This is the third sensor I’ve put in there. Currently I think it is the Bosch 13077. The sensor seems to be reacting as it should. I did the test where I simulate a lean condition and a rich condition.

    Yes sir, i agree it should not be 1.5v, nor any voltage there at all. What do you think is happening?
