rough idle

[chimp]

hi, i have a problem with my car its a 1.8t, engine code AUQ. when it starts from cold the tick-over starts at about 1200rpm and then drops down to 800ish, at this point the needle fluctuates up and down slightly and there is quite a loud flappy type noise (almost like the rotor noise of a helicopter). it seems worse if the climatronic is on. when i drive off it is then very unresponsive and jumpy. is it a simple cure or something far more sinister.

hey fella,perhaps the amm needs replacing or even the temp sender????

cheers for the reply slim, i might sound a bit dopey but whats the amm. the temp sender i think was changed last year when i had a coolant temp fault.

if you have a look on the "search this forum"tool,there s lots of info on them they're also called maf,mas airflow meter.tells you how to see if its not working.
Mind you it could also be the throttle body needs cleaning,just a idea???

i have the same problem with my golf gti,i replaced the maf sensor,n75 valve, and temperature sensor and cleaned the throttle body but this didnt solve anything.
the garage are saying its the fuel pump that need to be replaced so i cant believe in them anymore
