Unplugged Idle Control Valve 1990 300 SEL

[abram]

All this started with with a hard to start car with ABS light on. I had a blown OVP fuse in my 1990 300SEL, I replaced the fuse and the car idles 1600 rpm and is easy to start, when i remove the good fuse, it idles normal but is hard to start. I Know the OPV will have a lot to do with hard starting, here's my question. What i have found is that when i disconnect the idle control valve, the car idles at 600 rpm and runs normal, with it connected it idles high. Is there a problem with driving with the ICV unplugged or will it affect the cold start value? I drove 10 miles today with it unplugged and all seems fine. Another questions is how many volts should be at the ICV, i am showing 2.16 volts. I have also cleaned the ICV and when i put power to it i can hear it operating, 12 volts only, with it connected i cant hear it operating with 2.16 volts. Not sure if all has to do with the OVP relay or not, I tried to find one at a salvage yard today but no luck.
