I have the same car with the CIS. I use my hand throttle to start even on warm days aftert he car has cooled down. Before, the plastic peice for the handle throttle linkage was broke and it barely held idle on its own. Now greatly improved.

I replaced my warm up regulator as well. If your not using the hand throttle on start up then do so and wait til the car is waremd up til release. If thats not the problem, try getting the pressures checked on the WUR. Check the hose on the idle stabilizer (bell shaped unit just behind and on the left side of the airbox. That could be your problem.

Their is a great CIS checklist under Tech. Notes that you can copy and use as a troubleshooting guide for the CIS. I had to learn the hard way with repleacement of the airbox, cold start valve, WUR, injectors, hand throttle linkage, idle stabilizer, fuel accumulator, etc.

Once the CIS is working properly life is great!!!!
