    Default Tickover Issues After Cleaning Throttle Body

    Well my little issues with car being a liitle hesitant and tickover dropping down every so often are sorted now after taking throttle body off and giving a a thorough clean with carb cleaner. Now the car has gone a little silly on the tickover. It drives lovely but when you you let of the throttle it holds at 1500 revs for about 30 seconds then drops down to 700rpm. Its a bit of a cow when in traffic. I noticed and was very suprised to see there is no paper gasket on the throttle body as well just the rubber seal, is this normal.Could this just be something simple its got me baffled.

    Just smear a little engine oil on the seal and dont over tighten it. Take off the battery for 20 mins (making sure you have the stereo code) and then the idle should sort itself out. the ECU has become used to the amount of air it was getting with a dirty throttle body, now you've cleaned it its getting more air than it's used to so it has to re learn. Its this gap around your butterfly that controls the idle.

    No probs m8. The only other thing it could be is an air leak caused by over or under tightening of the TB bolts. A good nip up is all they need.
