    Oil sensor casues shake/studder. Please help

    My 2008 5.3 started doing this last week and I figured it was the torque converter and old tranny fluid. I have a hard 1-2 shift, so I was going to do a change/flush, replace the TPS, 1-2 accumulator and corvette servo. I'll diag the AFM switch tomorrow and see if it comes up. I just started...

    I've done just the ball joints and screw that. My last two were control arm assemblies and I never looked back.

    Is this rust a dealbreaker? 06 Z71 90k

    In the midst of replacing a corroded fuel pump. Crawl under it with a flashlight and a mirror and see if it is rusted. That's better than throwing parts at it.

    Do you fully fill your tank or partial fill?

    My Pops is a mechanic from way back and he has a good take on this. Since the fuel pump is submerged, it actually uses the fuel to bleed away heat. Sounds legit.

    2007 Yukon 5.3 Flex fuel supply line

    After smelling gas and getting worried, I decided to drop the tank and take a look... WOW. My fuel pump was wrecked with corrosion and a line just about to puke. The only way to remove the fuel supply line from the hard line was to cut off the connector, so I am screwed. I REALLY don't want to...

    p0455, smell of gas, slow starting

    Well, I've not found the stumble issue, but my pump is dead. When trying to disconnect one of the lines (that was quite corroded, btw), it broke off completely.

    p0455, smell of gas, slow starting

    Sorry to bring back a deader.... did you have a slight stumble at idle also? Other than that, these are my symptoms.

    Hate to bring back a dead thread, but I am experiencing the same issues.... extended crank, p0442 code and additionally, I smell gas fumes from the driver rear. What was the fix?
