What are these 2 sensors on the throttle body? Cars running really lumpy and found out that the sensor at the back is the culprit. Just want to know what it is so I can change it!

#2The rear one which is more then likely causeing your problem is the ICV (idle control valve) have you tried to clean it mate ? -
#3Nah mate i havent. Do you just unscrew it and clean it?

#4Pretty much if you have a search on here there is a guide, easy job to do and normally fixes dodgey idles.

#5Cleaned the ICV and it worked really well for a wile. Started it up a bit later on and as soon as you put ur foot on the accelerated it cuts out. Kept starting it an eventually I could accelerate without the engine cutting out now the car pulses on it's own. Got a vid below of the revs pulsing (bearing in mind that I'm holding my foot in the exact same position throughout the vid!)

#6Remove the whole throttle body, unscrew all the valves and sensors and spray them all with degreaser or carb cleaner. Then spray a little WD40 onto each of them and do the same thing to the throttle body itself.
Spray a little carb cleaner into the inlet and screw it all back together.
Should work ok then, if not a new ICV would be the next step -
#7Yea I've cleaned all the bits. Can you squirt carb cleaner into the actual connectors for the sensors? I haven't done that cos to scared that it will fcuking the whole lot up!
Would the ICV effect the revving even when trying to keep it al e.g 2k rpm?
