Please help me W201 gurus

Alright everyone,

Here goes nothing. I was thinking of selling my car, but now I think I'm going to toughen it out and stick with it and fix up my W201. It is a '86 2.3-16V. However, that means that I need help with my car and possible diagnosis on what might be wrong. I have my own theories, but I just want other opinions. OK.....
1) the accelerator sticking problem of course. Only happens when I'm boosting above 5psi it seems. I have to turn the car off with the key in order to stop the car. The car overboosts to 10psi. and more if I kept it running long enough.
2) on cold days, when starting, the car does not want to turn over.....this is different from the usual W201 hard start problem b/c on my car you can't even hear it firing. It just sounds like the starter is just turning the crank over and over and it is not firing at all. I have to use a starting fluid in order for it to try to turn over. Holding or pumping the gas pedal doesn't help at all. Very frustrating. However, on hot summer days or 60 degrees or more, it does fine.
3) recently when coming to a stop I'd take it out of gear and the RPM's would just drop all the way down to 0 and stay there. Very frustrating. Please help.
4) OK, it's been awhile since I started my car and everything was cool, however, now when I start it up, the ABS light comes on and stays on. Help me please!!

If you can help me out with any of these problems, that would be great. These cars can be very frustrating, but for some reason we all love em alot.heheheh......thank you.

you have a turbo or supercharger on your car? did you install it yourself, or have it installed? and how much did it cost?

About your problem Ive got a theory on the accelerator sticking. the added pressure of running boost is holding the butterfly valve open not allowing it to return to idle, this happened to my when I was tinkering with my lawnmower and a 12v blower, i couldnt get the mower to throttle back without lowering the forced air input from the blower.

about the hard starting, when last did you do a thruough tune up on the car, replacing plugs, wires, distributor cap, rotor, air filter, and fuel filter.

about the other problems ive got no ideas and am definately not qualified to give any oppinions as i have never experienced my tach going to 0rpm with the engine running, my car doesnt have ABS so i cant help there either

hope what I did know a bit about helps out

Hard starts, ABS light stays on, stalling..... OVP relay? Have you checked the fuses?

On you sticking throttle....does the kit come with a blow off valve or waste gate? Before you installed the kit, did you examine the throttle body carefully. No wear/play in the shaft or bushings? Could the forced induction be causing the auxillary air regulator/idle valve to stick open...

Just some thoughts.
