2003 A3 Idle problems

I have a 2003 Ae 2.0tdi sport with 72,000 miles. The idle seems to jump up & down between 800 - 1000 revs!! Ive had a major service & put a bottle of forte in the fuel with no luck! The error code said that there was an electrical fault in cylinder 4 so I tried changing the wiring loom under the rocker cover, still no luck! The idle seems to be ok when I turn the climate control on!! What can I do?? Please help!!

Audi A3, 2003,starts and then revs and starts to cut out,if I rev it up it settles back


Yes, if you have some work done or a part replaced and a fault develops in the same system, then the replaced part is the most likely culprit. A faulty O2 sensor will alter the mixture and idle settings.

My toledo v5 has a jumpy idle ive changed maf sensor cleaned throttle body changed engine temp sender still no luck jumps between 600-1200 rpm on idle never stalls thanks for any help


Do you perhaps have a small exhaust leak? Check ahead of the O2 sensor. If the exhaust can **** fresh air in it can't give the computer an accurate reading and the engine will rev up and down at idle. Hope this helps.

AudiA3 Bad Idle and rough at certain revs


buy a bottle or two of gas line anti freeze, it absorbs any water that may be in your fuel. add one bottle now and one the next time you fill up. if it is water as i suspect you will notice results almost immediately.

2003 montero sport. will not idle since battey boost

Intake manifold gasket is the most common cause of un-even idle.

IAC (Idle air control) motor is a small motor that adjust the idle.
In a cold AM,start up the car and turn on headlght,high beam,ac and radio.

Look for the IAC to see does it back down the idle as you shut off one item as a time.

IAC can be lube and save.
