Dead spot in acceleration from idle?
When I try and accelerate lightly from a stop, the rpm jumps straight to around 1800rpm. I have tried pushing down slower and softer, but no dice.
I've gone into the engine and tried pushing the throttle by hand, same result.
There is like a 'dead spot' ?
I've measured the voltage on the TPS and that appears even throughout the range. Haven't measured the resistance tho.
Any ideas at all, this is driving me up the pole!!?
