I know this is an old subject , but a recent tweak of my TPS gave me an unexpected bonus.
I previously had adjusted my TPS counter clockwise, so the the unit would not shut the fuel off at closed throttle, and richen
the mixture a little sooner at the other end..
I was never really happy with the closed throttle feel, so I decided to take the easy way out and cut the
black and white wire.
Low speed fuelling is definately a little smoother , with wide open throttle acceleration remaining really strong.
I recently noticed at idle the motor was hunting a little , not a lot, as if one cylinder was slightly out , but it
was there .
Since I cut the TPS wires, the hunting has gone, and she idles at 1k steady as a rock.
There has been a slight reduction in the buzz during 5th gear roll acceleration.
