ok now I have another problem, as alot of you know there are 2 stages to the accelerator pedal half way and then full basically, when I put it to the half way stage, there is kind of like a ticking noise coming from the engine, but when I drive normally its not there and when I rev the engine its still not there, only when I put it to the halfway mark, I have not heard it when I have had it flat yet as the engine is probably too noisy to hear it... any ideas?
