Ok, So I reinstalled my newest TPS sensor and I simply calibrated C to D to open infinity at feeler guage thinness .020. Done deal....
I was not able to test the fuel pressure but that may not be the issue after you hear my descriptions below:
1) Ohms tested air intake temp sensor cold ~ 2800 ohms - after motor warm up and good hot drive - 400 ohms. Seems good.
2) Ohms tested water temp sensor cold ~ 2800 ohms - after motor warm up and good drive - 300 ohms. Seems good but.....
I decided to start unhooking sensors like you mentioned with the 02 sensor. Made no difference. Misfire persisted... then reconnected.
Then unhooked the air intake temp sensor and misfire persisted. then reconnected.
Finally I tried the water temp sensor and it drove perfectly with no misfire and I was able to rev to 5000 rpm under the same light partial throttle.
Ran really good but was running super rich at idle. But no misfires which was a huge improvement.
The water temp sensor is making contact with the computer because I can see the air fuel ratio change as soon as I unplug and replug it. The simple ohms test seems to make it look like its working correctly but I am not sure. As the Suzuki cools off I have been testing the sensor and it appears to vary its ohms readings correctly.
Note: My timing has never advanced either when it revs up. It seems locked out all the time. I also tested this with the coolant sensor disconnected as well.
