    Reduced Engine Power - on startup only

    No battery issues. I replaced the starter and have not had the REP code since. Seems it was related to the starter going bad.

    Reduced Engine Power - on startup only

    2003 Yukon, 245k miles, 5.3L 2wd -- I started getting the Reduced Engine Power warning a few years ago not long after I bought this truck used from the 1 previous owner. For a year, I occasionally got the REP warning, maybe once every month or so. Then, it seemed to completely go away this...

    HELP! Strange Sound coming from AC

    I recently bought a used 2002 Yukon 5.3L and I have this same exact issue. Exact same symptoms. Did you ever figure out what it was? What fixed it?

    Could a broken chassis-to-hood ground strap cause my battery to drain and various CEL codes?

    Hi All - appreciate your thoughts on this. 2003 GMC Yukon 5.3L 2wd with 175k miles. I've been driving these 00-06 Yukons for 22 years. Had a 2000 that I put 400k miles on, and a 2005 that I put 300k on, and I love these 00-06 model years so I bought this '03 used a year ago from the original...

    Instrument gauge cluster repair -- overnight parasitic battery drain

    Looking for advice and recommendations. I've been trying to track down the source of a parasitic battery drain on my 2003 Yukon SLT 2wd 5.3L with about 180k miles. I'm the second owner, had it for about a year. Always garage kept (per the prior owner). BACKGROUND: A year ago, I put in a new...

    Which battery (AGM or Wet) came stock in 2012 Tahoe?

    I'm trying to figure out what type of battery came stock in my 2012 Tahoe (second owner), 5.3L, 4wd, LT. Is there anywhere I can go to figure this out? I know if you've got a AGM you're not supposed to replace with wet, but if it came with a lead acid battery then you can install an AGM, right?

    ???Battery Recomendations??? Best Battery???

    Weighing in here - Optima Red Top seem to be garbage now based on my experience. My first RedTop (got in maybe 2004?) was great - ran for 7 years. Have had terrible luck with 3-4 of them since. One went about 2.5 years and crapped out, so it was replaced by AAP under warranty. The...

    Two Tone Yukon Denali

    Is there a two-tone available on the Denali or other model Yukons that I don't know about, or is this an aftermarket job? If this is available, I want it. I think it's a killer look. Everything else about this Denali looks stock (even the black wheels are stock GMC wheels), which makes me...

    Oil Catch Can

    I have a 2012 Tahoe 5.3 and a 2003 Yukon 5.3. I’d like to install catch cans on both. Any recommendations for the best product (part numbers or links are helpful too) for these applications?

    What Year is Reliable

    I really like the 99-06 vortec 5.3 motor. I bought a 2000 Yukon new. Put 400k on that motor, replaced one trans. Bought 2005 with 191k on it. Ran it up to 300k on original motor and trans and gave up on it when the trans went. Just bought a 03 with 150k and it runs like new. I also have a...

    Dielectric grease applied to both ends of ignition wires

    It’s entirely possible there was nothing really wrong with my cat but the code was thrown from the intake leak??? But, I fixed the leak and had the battery disconnected, the codes reset, and then came back after the leak fix. So I’m not sure if it was a true cat problem or not. The cataclean...

    No oil pressure at start up, 2001 Tahoe

    I put nearly 400k miles on my 2000 Yukon 5.3 2wd. Original motor, did replace the trans after 161k miles. For about the last 100k miles I had this same low oil pressure on startup issue. Wish I would've known it was such a simple fix. In the end, it had some other issues when I finally gave...

    Dielectric grease applied to both ends of ignition wires

    Just wanted to report back on my original post. My CEL with the same codes (P0101, P0102, P0420) came back on about a week after I had the battery disconnected. I ran some CataClean through the fuel tank and the CEL went off within 50 miles and has not come back in over 1,000 miles. I have to...
