James, that's good info. I did find where the harness rubbed through the loom that goes the the ICM, I looked at the wires and it didn't seem to get to them. I'll take a closer look when I get a chance and split the look and look at every wire the other wires by the crank sensor everything is good. I had a good chance to look while
I was changing knock sensors.
Bandook,
When I was able to get the KR to read I could start the car let it warm up a little while I gathered stuff and whatnot. I would back out of the driveway and as soon as I started off the air would read 2-3* then jump to 15* then drop off as RPMs increased, the. Drop to 0. It was very erratic and some days it would other days it wouldn't. So I know it was pulling KR at that time. If KR works nothing else does, can't read ignition timing, MAF, Map or anything else. I had restarted the phone, reinstalled the app, deleted PID's I didn't need basically everything Kevin at BAFX recommend.
Corey,
I am not sure that the 04+ will do that without setting a code. It would be easy for the ECU to ping the sensor to see if it was there. I'm not sure it actually does this, but the thing is smart enough to reduce the throttle opening compared to the pedal input so the programming is pretty good at protecting the engine. Besides I did the above and changed both sensors front and rear, now it doesn't do the off idle knock but I'm getting the other problems I mentioned.
my LTFT on a 40 mile drive was -15 to +15 and my STFT was -6.2 to 0 this was almost all freeway with about 10 miles of highway with stop lights, this was earlier today.
now last night I really had something strange. I drove to a friends and when I left I was monitering 02, MAF, temp, intake temp and timing. Normally my 02 is real spikey which I see as normal for a narrow band 02. Then I was at a 30mph roll and stomped on it WOT well the engine started taking off and I was watching the MAF and it was a linear rise then started to taper off (I could feel the power start to drop) then the the MAF voltage dropped off and leveled out even though I had it floored. Timing reduced to -3 and then the engine started acting a little weird. The 02 stopped switching back and forth as quickly it would show rich for several seconds then lean for several seconds. When I pulled into the driveway it was still doing it. Shut the car off and restarted it and everything was back to normal.
i have had several times where the engine goes into reduced power. The other day I noticed one of my friends was ahead of me and I kicked out into the next lane to catch up. Got to about 3psi then let off then the HUD says check DIC and it's going through the traction control off reduced power and all that and when it does it sets the timing to 15* ATDC and dead rich. I quickly pulled over and shut the car off opened the door closed the door and restarted it then drove off like nothing happened.
