: Hunting idling

4th May 2002, 05:34 PM
Hi guys, could you give a advice about My cars hunting idling.YouŽve discuss quite much about that topic, but I cannot find the direct answer for my problem.
The Car is 9000 Turbo 16V 1989 , B202 engine, with DI, APC, and one ECU. Car has new AIC, Dumpvalve and Ignition cartridge. Problem is, that the idling is moving between 800- 1500rpm, as like the engine system tries to fix the idling. Car has not used in 4 months. IŽd like to know, what would be the first place to search the problem. I believe, that there is no vacuum leaks, and everything else is ok. Thanks for your reply !!

I had some problems like this with my old 9k and it turned out to be corrosion on the connection to the air mass meter
this was an 87 non di t16

its a long shot but an easy check

this prob "haunted" me for ages

If you have checked for air leaks then this does sound like an AMM problem, but these things are always difficult to diagnose. If possible you ought to try out a know good one.

Thanks guys, the throttle valve box was very dirty, + airmeter wire was without that string, which thightens the connection + there was corrosion. IŽll fix those, I hope it works after that, Cheers!

What is AMM?
