Well, now. First, check the OVP, if it's out, it will run funny. Check the idle mixture, and also (first) for vacuum leaks --we just replaced the idle control valve hoses and the boot between the air meter horn and the throttle body.
Squirt some brake parts cleaner over the idle control valve hoses and the boot -- if the idle changes, replace them, and replace the injector seals AND the o-rings on the sleeve the injector fits in -- they all are bad if any are bad. Vacuum leaks will drive you nuts on that car, as the computer controller won't set the check engine light when the mixture goes out of control. If you have occasional stalling when coming to a stop and/or throttle lag, suspect a serious vacuum leak. The warm start problem is quite likely a leaking accumulator (will also cause hard starts in really hot weather with the engine hot) -- you need to have the pressure checked, it should be 3 bar with the pump on and something like 2 bar indefinitely with the pump off.
