Little update not sure if this matters or not. I was messing with the car again Saturday and as the idle was fluctuating between 600-1500 I unplug the sensor on the side of the air flow housing it the fluctuating idle stopped the same was as when I unplugged the idle control valve. I am starting to thing that something that tell these things what to do may be bad. I also replaced the OVP and that did not help at all.

Maybe someone could reply with a step by step for tracking this down and I will try that. Letting the dealer look at it already cost 475 bucks and it's pretty much still the same. Plus the car is pretty easy to work on, I am just not familiar with what readings I should expect.

Thanks

Also a 1988 300e cd would be nice, if anyone knows where I can find one.
