Hi Guys,
Popped a new Bosch MAF in the car and same problem! I guess we can rule that one out.
I've identified now that the problem occurs even when not at speed, so if I squeeze the throttle on it seems to be fine, if I dump the accelerator to the floor to hit kickdown at any speed the car bugs out.
All gears remain, however the throttle response is nearly non existent!
Pressing the pedal fully again achieves nothing, the car doesn't accelerate, gently squeezing it gets to perhaps 50% of the pedal movement then starts to pick up, even in neutral.
I've got it booked in to get the codes read, but could the kick down switch cause the throttle to behave this way if faulty? Similarly, if the throttle is stamped down quickly would a faulty pedal position sensor bug out?
A quick stop and start solves the issue. If I keep the throttle pressed to the floor at low speed it will accelerate and pick up beyond 3k rpm, however I suspect the issue I had when at speed is that more throttle is required and there just isn't any there, so the car is sluggish, hardly pulls and lingers around 3k.
Cheers,
