Plugs new
Tested lead resistance - all within spec
Tested coils - all within spec
MAP sensor OK
When testing TPS resistance - the resistance does jump at some places. I'm not sure if it's because of the physical mechanism being pushed in a bad way (even though I'm doing it softly with a screwdriver it's not as smooth as done by the rod in the throttle body).
I guess my question is: can a faulty tps cause intermittent misfire symptoms?
