Car Wars: Detonation Strikes Back

Have you reset the computer since you changed the TPS? If you haven't, that would explain why the continuous code is still there. It's also a good idea to reset the computer after changing a major sensor like O2 sensors and TPS.

What voltages are you getting from the TPS now?

Have you done a Key On Engine Running test and what were the results?

What is the timing set at and did you check it with the SPOUT jumper removed?

How hot would you say your car gets when this starts to happen?

Do you have a friend that you can exchange MAF sensors with when it starts to act up?

I did reset the computer after the sensor change. Although I have not yet checked the voltage on it now. I was going to do that this weekend.

The KOEO Test has been doing the same thing. I have not done the KOER test since the TPS change.

Timing is at 10*, changed with the SPOUT removed. The timing with the SPOUT in, I never did check that after I changed the timing to 10*. But when the timing was set mechanically at 0*, with the SPOUT connected the Timing was a little over 10* (11 maybe 12)

Heat, well I have to go by the dumby gauge in the car, but once it reaches the "N" in "normal" things get funny. If the A/C is turned on the temp will shoot up past the "M". I assumed that this was from the detonation.

Unfortunately the only guy I know here in Dallas, is Hammer and he has a 98 (not stock) and an 83 (not an MAF car).

I'm also running Mobil 93 Octane fuel.

Do you think if the EGR was plugging that the combustion temperatures could get hot enough to start the detonation? That was one of my theories, what do you think?
