98 Audi 1.8l idles low sometimes, but . . .

imported_jimmy154 Jun 23, 2010

  1. it is very specific in that it happens when something requires power from the engine at idle. Say you turn the wheel the idle drops when you stop it goes back to normal. Or the harder I brake when I come to a stop and the engine is at idle for a second while I am coming to a complete stop the more the idle plunges. Or if I have the AC on this makes all these problems worse. Putting the car in reverse also causes the idle to lower and occasionally stall. If I turn the wheel while putting it in reverse it has stalled. I was going to clean the throttle body tomorrow and MAF sensor, but I don't think that would cause a problem such as this would it?

    Mine did similar and cleaning the MAF with electrical contact cleaner worked a treat.
