    Throttle Position Sensor Issues

    Good morning, I'm hoping someone can help me figure out what my next steps are for diagnosing and issue with my TPS. I was having issues with the truck when I got it where it was shifting poorly and not making as much power as I thought it should. So, I checked the TPS and sure enough...

    Risks of driving without TPS?

    Hey guys, I have a 94 k2500 with 5.7 and 4L60E. Sat in a field for about 11 years before I rebuilt a donor engine in it and have driven about 2000 miles on the break-in. Before I got my hands on it this truck had the tbi swapped for a carb and appropriate intake (Holley 4160 and Edelbrock...

    Possible 1-2 Shift Solenoid?

    In January I went on a 2,000 mile road trip (mostly freeway) in my 1993 GMC Yukon GT (automatic). Probably 100 miles before I got home, it started doing this thing where it wouldn't shift out of 1st unless I got the RPMs to at least 2500, let off the gas for a second, let it shift, and then I...
