99 impreza turbo low idle prob, seeking help

Hello all, have a 99 impreza turbo wagon with low idle prob, revs from 300-1500, won't remaid stable. Garage checked the idle motor & transmission switch (even though it's a standard) and checked all reachable vacume hoses and haven't solved prob. Anyone have similar prob? What was the cause ? Funny enough this problem became worse after I had the plugs changed. I'm not a mechanic and will have to take it back and let them try and see what they can find $$$$$$.

Any help would be appreciated.

B.Rgds Paolo Ch

Have you checked the coil pack??? Is it misfiring??? Did they change the leads as well as the plugs??? :shock:

Sounds along these lines to me matey. See here - http://www.subaru-impreza.org/subaru...pic.php?t=5763

It could also be your MAF sensor (this is known to cause an unsteady idle).

Hope you get it sorted mate,
