Some people like doing those crazy sudoku puzzles. I like debugging and fixing broken things. Below are notes from random fixes I've performed where I haven't had time or ambition or interest to create a separate page with pics, etc.
Problem: Unit is stuck in CW mode, buttons don't work. Reset does not help.
Radio diagnostics show a stuck bit for the tuner. Hmmmm.
Problem: Low receive sensitivty for narrow FM.

Update: Turns out that KD0FER had a deaf VX6R...searched the forums...ended up here...and then realized the he knew me. We took a look at his radio over lunch and I was confident it was the same problem. Super deaf on NBFM receive. Just fine on WBFM receive. I brought some tools and my extra filter and we went for the repair. Another success!

Ok, lots of stuff can go wrong here...
Problem: starts OK, bad performance (can't get above 1500RPM) for maybe two minutes after first start of the day. But not at all after it's warm.
Troubleshoot:Disconnect upstream O2 sensor. Better?
Solution:If disconnecting the upstream O2 sensor makes things better, replace upstream O2 sensor. This is a heated O2 sensor and the computer relies on the readings from this sensor for air/fuel mixture. You get bad values from the sensor until it warms up by virtue of being in the exhaust stream which takes a few minutes. Once it warms up, it's fine. If you disconnect the front O2 sensor, the compute runs off an internal air/fuel map and things aren't optimal but they're better than with a bad sensor.
The front O2 sensor isn't bad for replacement, you can put a standard O2 sensor socket over the sensor and a breaker bar will fit atop. Hit the sensor with penetrating oil and then push at the breaker bar with your foot. Remove/replace. Done. Mon Aug 13 11:22:47 CDT 2012
