    The Dreaded P0300 Code: Solved

    I wish I was so lucky to find a similar solution. My 2003 Tahoe (LT 5.3 V8) has had an intermittent misfire condition for nearly 5 years. I've been to multiple repair shops and I have replaced the following based on their "expert" diagnosis: - spark plugs - spark plug wires - coils...

    2003 Tahoe windshield wiper issue

    The delayed settings do not work as they are supposed to. Any delay setting simply does a continuous sweep.

    2003 Tahoe windshield wiper issue

    Sorry, I've been off line for a while. It turned out to be the motor; I thought. I replaced it with one from NAPA in July and tested to insure all settings worked appropriately. I don't drive the Tahoe much and summers in July are typically dry. Today we had a little shower. At first the...

    2003 Tahoe windshield wiper issue

    When the intermittent wipers are on for 10 minutes or so, they start doing a little stutter-step at the start of the return sweep. This problem has gotten progressively worse over the last 6 months. If I switch them over to the "regular cycle" they will be okay for a while, but them start to...

    I'm new! 2003 Yukon Denali

    We do probably have an infinite number of places to off-road in Oregon. I'm in Corvallis but don't get off the beaten path much. I have a 2003 Tahoe, and am curious what you did for an audio system. I have a Bose system but the radio/CD needs replaced. Mike

    Transmission flush.. checklist!

    I have a 2003 Tahoe. Purchased 4 years ago with 145K. Changed transmission fluid then. I'm always interested in improvements. Curious about what year vette servo you installed? Also, how difficult was the conversion? Thanks

    Engine Misfire on Cold Start - 2003 Tahoe 5.3

    Symptom: Engine will run rough on a cold start. This is an intermittent problem that is totally unpredictable. If it happens it only happens on a cold start. It will continue to run rough until the engine has warmed up, and has been turned off about 30 seconds and restarted. Then it runs...

    Replacement Bose CD Player for 2003 Tahoe

    I have a 2003 Tahoe with the Bose entertainment package. The CD player quit working about a year ago. I installed a used CD player from AliExpress but couldn’t get it to work. It would load the CD but not play (or eject). I’ve checked out a few local car stereo shops. They have nice quality...

    2003 Tahoe 5.3 - Random Multiple Cylinder Misfire

    Kraig, I appreciate the response. I'm only a backyard mechanic, so I'm curious how the intake manifold affects the current symptom which is: when starting the Tahoe it runs rough until it's warmed up and then restarted. I'm not sure how long it would run rough if I didn't restart it, as I...

    2003 Tahoe 5.3 - Random Multiple Cylinder Misfire

    I want to thank everyone for the feedback. Here's what I did following the feedback. Checked cat (no rattles), changed plugs ((gap = .060) and plug wires. The random rough running returned a few days later. I then changed the upper O2 sensors. It ran smooth with not issues for two weeks...
