    '14 Suburban: Tachometer Reading Off

    Traveling down the highway about 60 mph and the tachometer all of a sudden dropped about 500 rpm in its reading even though the engine continued to run fine. Traffic slowed to about 15 mph and the gauge dropped to zero. Engines been running good, like normal, but the tach is off. No engine...

    P0307 + P0300 Misfire - '14 Suburban

    I'm getting both codes together, P0307 and P0300. Every time I read about both occurring in my search, everyone pointed towards the fuel injector. Wouldn't say engine runs rough, it just has a periodic 'hiccup'. It even took a while for the check engine light to come on. Occurs the whole time...

    TPS Issue

    There's connections within the fuse box and underneath it. The bulletin only mentions those under the fuse box. i inspected those and cleaned them even though they looked really good. I think the connections within the fuse box appear to have been the culprit. They were dirty and corroded...

    TPS Issue

    Thanks, I'll need to review. Following the Bulletin, I removed the fuse box to inspect the connections. The majority started to show corrosion or were dirty so I sprayed it with a contact cleaner. I also went ahead and replaced the associated Fuse #5 for the ECM / Throttle, just in case. Put...

    TPS Issue

    Found a Service Bulletin that is related to this issue. No.: PIP3783D Majority of the Conditions, Recommendations, and Instructions relate to potential shorts to ground or high voltage drops between the APP (TPS) and ECM. It points to pin outs C109/X109 and C205/X205 for review. I'm hoping...

    TPS Issue

    That didn't last long. Threw codes and went into limp mode twice this morning. Had to clear them quickly as it was not safe so I'm only assuming it's the same codes. I don't know what to do next. Replace wire loom plugs? Should I just give up and take it to a repair shop? I don't want to...

    TPS Issue

    Hopefully the last update; After all of the issues with replacing the Throttle Body, I was finally able to force the Chinese Diagnostic Tool to setup for a different GM model to wipe codes and initiate a throttle position relearn before sending it back. The throttle response and engine power...

    TPS Issue

    Slow boat from China and they sent me a used one even though I ordered new. Box opened, missing charger cord, and finger prints all over it. Even had the PO email and contact info stored. Going to return. Wouldn't trigger a relearn but was able to pull some diagnostic data that I wasn't able...

    TPS Issue

    Is the Tech2 the only way for us to trigger the relearn for the Throttle Position? I also have a Toyota Sienna that's needing it as well. Would be great if there was a scanner that performed this function for both like the Launch CRP129E Local shop will perform the reset for $80 each but I'd...

    Throttle Body Relearn

    Put the Old Original back in and now it's acting up for even that one. Got the Hitachi and it does not have the GM stamp on it like the others but it looks much nicer and was packaged much better. Even after sitting over the weekend with the battery unplugged (which also allowed a thief to...

    Throttle Body Relearn

    This really sucks. Picked up the replacement and installed. Idled at the typical RPMs but ran extremely rough and threw different codes triggering limp mode, stabilize and traction lights, etc. Ran 3 minutes, waited 1 min and then retried with the same effect. Stopped the relearn process...

    Throttle Body Relearn

    Thanks for that. If that is the case then how is ACDelco also claiming to be the manuf? Since the TPS Pedal Assembly and TB appear to be related and talk to each other or both to the ECM about what is going on, then I'd lean towards them both needing to be of the same manuf to eliminate...

    Throttle Body Relearn

    Oh yeah, saw that. It's about $150 in difference. Figured with the weird issues I'm having, didn't want to take the chance of introducing something else with what might not be OEM. I learned the hard way when I swapped in an OBDII fuel injected engine into my old Jeep and tried to save some...

    Throttle Body Relearn

    Put the old one on, and all is fine. No codes. Before and after Relearn procedure, idle is ~740. Going to exchange.

    Throttle Body Relearn

    Here's photos of the OEM that was on my vehicle and a pic of the new ACDelco. Where does it say Hitachi is OEM? Both have the GM stamp, same model # and QR Code.
