    P0171 & P0174, Fuel Pump?

    Fuel pressure gauge connected to the Schrader valve. Fuel pressure started dropping lower than 40 when I let off the gas pedal. The warmer the engine gets the more symptoms I have it starts running like crap.

Pulled codes P0171 and P0174. Checked fuel pressure it was 52psi with key on, when started it went to 50psi then dropped to...

    Please help. P1516 and p2135

    I had it running, asked my friend to shake the pigtail off the connector, when he did the engine shut off and he was zapped by one of the wires. I cannot find any breaks in the insulation. It shocked him somehow though. Opinions please.

    Please help. P1516 and p2135

    About 6 months ago my 2007 Yukon service stabilitrak lit up and I was accelerating but not going anywhere. I shut the engine off sat for a few minutes then it started right up and ran like a champ. This happened 2-3 times over the next 6 months. I did put the OBD ll on it one of the times and it...

    2007 Yukon 5.3 rough/sputtering idle while in gear at a stop. Runs great while accelerating.

Did this to...

    I'm having a heck of a time finding a transmission. So the 2009 Silverado & Sierra transmissions will bolt right up to my 07 Yukon?

    What vehicles have the same transmission

    I have a 2007 GMC Yukon 5.3 liter, 4wd, 4L60e transmission that the clutches are welded together. Cooked. What other vehicles and years have the same transmission as my Yukon @NickTransmissions ?

    Transmission has turned Christine

    I apologize for forgetting a very important factor in my post! Thank you for your advice. I've been waiting and hoping you'd eventually read my post and tell me your professional opinion. I am going to have to go with a used transmission. Can you tell me what vehicles and years will be a "plug n...

    Transmission has turned Christine

    All the shops I call won't do any bi-directional testing on it. They all go straight to "You cooked the transmission so it needs replaced." My gutt tells me it's something that's not major but can't get anyone to actually look at it. I forgot to mention that while in neutral it wants to move...

    Transmission Cooler Line Popped Out/Update

    I changed it because it was leaking, spraying right on the PCM. No I did not change the thermostat. I knew I should have & kicking myself for not.
