Hello everyone,
I got a 2003 Tahoe LS 5.3L 2WD with 260k miles and paid $2000. Been lurking around these forums and have been successful with making a lot of repairs to this truck. I picked up a clone GM Tech 2 as well as got the GM esi Windows XP workshop manual, and those two alone as well as this forum have made troubleshooting and repairing so much easier. I had a misfire issue and was able to determine which coil pack was bad. ABS light which happened to be a bad front speed sensor. AC compressor went out and was able to use the Tech 2 to see all the sensor data and check my HVAC control unit. Clear out CELs, do a fuel trim relearn. Only got one check engine code: P0430, and plan on gutting the cats and using an o2 spacer on the rear o2 sensor. Been looking at various mods to do like the electric fan conversion.
Other major issues are the notorious lifter tap on the driver wide when initially cranked up, and need to tackle the loose steering (made a post about this a little bit ago). As well as determine why the mpg is kinda low for highway speeds and the exhaust smells a little rich. Probably has to do with the catalytic converter issue.
