Is this my TPS?
Okay, I have noticed recently that when I lift off the accelerator pedal not a lot happens to start with then all of a sudden it starts slowing (as it should).
I have cleaned the throttle body out and ICV (with new gasket) and checked the action of the spring that operates the butterfly valve.
This is the second TPS that has been on the car after the last one threw up an error code. I am not getting any error codes that relate to it this time.
Could this be something else? Camshaft/Crankshaft Sensor etc??
I'm stumped!!

It could be as simple as a sticky throttle cable.

It's a new cable mate, worth greasing it up?

got enough slack on the cable???
Know they often have too much, just wondering if its a bit tight and if that would affect it.

I think we have the same issue. It hasn't bothered me much to now though. When you lift off the gas, it's like she doesn't respond for a full second or two.
I was thinking it's the throttle cable too as very occasionally, when I have lift off and disengage the clutch, the engine continues spinning at 3,000rpm!! Blip on the accelerator pedal and it's back to normal.

When I fitted twin choke webbers to my Lada I got the return spring on back to front - that was interesting.
