Hello. My name is Mark and I will be assisting you today.
How high do the revs go and for how long. If it is around 1200 rpm for a few seconds then that is ok.
revs to about 2500 rpm for 30 secs or more does everytime you come to rest
That sounds like something is sticking.
Recheck the throttle housing to see if anything is in the way.
Idle speed control valve could be sticking or you have fitted a faulty throttle body.
as i said b4 new throttle body has just been fitted
And it could be faulty
doute its a gen part
Is your throttle body motorised or is the one with a throttle cable
I've seen plenty of new parts faulty
If its a cable then also check cable tension and throttle switch is set properly
cable tension ok throttle switch is preset in housing
Does the switch make a clicking sound when you move the throttle slightly?
switch was working ok have sorted problem myself
expect my £22 to be refunded due to sorting problem myself
