Hi all,

Wondering if you guys could help me with regards to a idle problem.

Normally the car is ok but now it seems to idle funny when cold the rev's stick at around 1500rpms and sometimes when warm the car chug's and you can feel the whole car moving!

Any idea's on the causes of this? Things for me to check/clean?

It doesn't have any air leaks as we have check this over the weekend.

I'm stuck!

Throttle position switch could do with a check out.

what engine is it mate?

Apologies, its a M20 2.0

i would also suggest a good clean of the whole intake system with CARB CLEANER

Clean the ICV, the THROTTLE BUTTERFLY and give the TPS, as Brian stated, a clean too!

Given that there are no air leaks, im thinking it is the BLUE TEMP SENDER located near the rad. Its accompanied by a brown sender as well; replace both at the same time, very cheap from the dealer!

thanks for the help guys. will try something this weekend.
