over reving when i stop at lights etc

My polo was idleing pretty sh1te so i took off the air filter and noticed that the little plug that attaches to the carb wasnt attached so i plugged it in. The idlein was fine after that but now it revs on its own ive played about with the carb but nothin seems 2 work. Anyone know wat it could be ? cheers

probably the throttle position sensor was unplugged.

By the way its a throttle body not a carb if its the polo in your avatar.

Disconnect the battery for about half an hour then reconnect it, will reset the ECU and should realise that the throttle position sensor is now working and set it in the right place.

nice 1 mate i will try that thanks alot .

i did this to my old polo and it cured the problem, it will run crap for a start but will settle down

realy, ok thanks m8

I tried it and it didnt work

get some brake cleaner and an old tooth brush, clean the throttlebody out then reset the ECU again, sometimes they get gummed up and hold the throttle open a bit

I have a 1.4 throttle body and ecu if any use to you fella

doubt it will need new parts, zara(z-dubber) on here, her 1.0 used to all sorts of weird things, took the airbox off, cleaned all the breather pipes and cleaned the throttlebody after an ecu reset it was fine.

ok ill try that tiz thanks. I wouldnt know wat to do with an ecu

Is it a bad idea 2 spray wd40 around the throttle body?
