Thanx It's difficult to know where to start when you have such general symptoms, but here's what I'd do: Check that you have no vacuum leaks anywhere on your inlet side - check every hose and every connection. This is the biggest cause of erratic idle. Check your ignition system - how old are the plugs, leads, rotor arm, cap? Clean out the throttle body and the AIC valve using some carb cleaner spray. Let us know how it goes. -- Grunff
