OK, thanks. I am really sorry this has drug out for so long. I am usually pretty good at trouble shooting this kind of thing, but this Rice Burner has been kicking my butt.
* Just to be sure, the front cylinder is #1 - Correct? (yes the most forward cylinder is always #1 on all engines, even V engines and boxer) it the one most close to the belted end of engine. near crank pulley on all engines, RWD or FWD.
* It misses or cuts out like the key was turned off when I am driving at just above closed throttle. In other words, it seems about 1/8th throttle. ..... but, it has on 2 occasions gone into that stumble and would not come out of it no matter what throttle setting.
but what if you stomp the gas pedal, DO YOU HAVE FULL WOT POWER NOW??????
* No codes to read as it has not set codes since I cleared the #1 Mis-Fire and TPS Codes. (but to get them takes hard driving , hot engine , one drives other scans)
* It will idle smoothly for hours with no indication of a miss.
* This problem does not seem to be temperature sensitive. It acts the same hot or cold.
Steps I have taken:
* Fuel System cleaner added 300 miles ago.
* Checked compression at 160 degrees. All between 185 to 190
* Purchased new NGK plugs and installed all 4
* Replaced #1 (Front Cylinder) COP
* Check voltage on TPS - it is perfect.
* Cleaned MAF Coils very carefully without touching them.
I will be checking fuel pressure when my kit arrives.
I will install new fuel filter when it arrives.
I could try switching #1 and #2 COP, but I have no way of knowing if the miss went to #2 because it only cuts out when driving and has not set a code again.
better is switching 1>2 injectors. front to 2nd. swaps. far better
What puzzles me is it seems to cut out at the exact same throttle setting every time I drive it, but almost always straightens out when I increase throttle just a tiny bit. I have to go like a bat out of hell or, let off the throttle to keep it from cutting out.
