gidpor - I was commenting on Oliver's post. Anyway, if its erratic idle at stops, the first thing to look for would be the air-fuel mixture - basic tuning. Then we look at the plugs and injectors before going on to the idle valve control. Sometimes we ave new plugs and injectors and just-tuned engines, yet the idle runs up and down a little. This could also be caused by dirt going into the idle valve and in which case, giving it a clean might just solve the matter. If having cleaned, and in extreme cases, replaced the idle valve and yet the problem persists, it could also be the OVP.

btw - whats the degree of play on your rpm?
