Yes - 124030 with the standard 103.983 engine.

I've been doing quite a bit of reading and feel like I need to check the Air Flow Sensor Potentiometer. The sympton seems to point to this device because - when I put the car in gear, the idle speed is reduced to around 600rpm (so smooth though, it's hard to tell the car is running) and I'm thinking that the potentiometer is "worn" at the spot that the car normally idles and that the computer thinks it needs to "speed it up" and does. Once it detects it has 'sped up", the idle drops down and we go through the same process again.

I've found a guy that sells an aftermarket Potentiometer, but I'm wondering if the quality is there (your input on aftermarket devices would appreciated as well).

Anyway, that's where I am in the diagnosis process - been at work all day, and I probably won't do anymore troubleshooting until Friday (need to keep my wife happy), but I certainly would "process" any insight you have.

I've seen your name on this site for many years and greatly respect your input, so any diagnostic input from you would be greatly appreciated.

thanks
