Howdy Cihan, I've tried setting TPS as mentioned in the TPS maintenance thread and achieved the outputs at those throttle stop gaps, quite touchy to set though, trying also adjust through minute rotations using trial and error too. Both without much success of improving in a big way. I have restored it as specified in the meantime though, which seems to allow the best compromise for sudden throttle back-off without awkward stalling through its rough idle. Thanks for the thought though
I have also tested the Distributor Caps with an Ohmmeter to test for continuity together with light tapping/shaking to ensure any loose paths don't show their faults, they seem fine too.
However as you've mentioned Mark, if timing variations occur due to a problem with Crank Angle Sensor wiring, this seems to be a possible cause as timing variations occur at lower revs where most vibrational disturbance exists, whereas higher revs, the problem in my case seems to level out to a more acceptable manner. Yesterday night, I removed and cleaned the Crank Angle Sensor, following the wire back up, it seemed quite tight between the body of the A/C Compressor and Fan Pump/Cylinder Block, but nowhere near the Serpentine Belt which rules out chaffing. I may have lightly squished the sensor wires during the A/C compressor refit. However with both ends unplugged, I will check for short/openings in the wiring, although not too sure about the white wire as other ignition components seem to share this wire on the Wiring Diagram. I may also be thinking too hard about a single cause/problem But, an idea is always better than none. I'll see, hopefully... Appreciate your time guys! Thanks again.
