Question about 1992 Mitsubishi Diamante
Sat for the last two years with maybe a 1/4 or more tank of gas. Wouldn't start, so just put a new battery in. Put some high octane gas on top of old gas and it would stall when come to a stop. We put Gumout injector cleaner in today. It comes close to stalling when come to a stop but hasn't yet in the couple hours since putting in the cleaner; but it comes close stalling because RPM's get down between 4 and 500 when come to a stop., Auto Zone tested alternator today and that's fine. They said to just keep putting high octane in from now on and do the injector cleaner once a month. But why does it idle so low when coming to a stop? Carburetor adjustment? throttle adjustment? did the 2 yr old gas really just gum it up? is it a computer issue with the idle control? I know it could be a myriad of things. Over two years ago it would idle around 800 or less also but not stall, I just want the RPM's up in idle!
Find the Idle air control valve on the side of the intake and then take off and clean or replace you could try taking a small ball peen hammer and tapping it lightly while it is idling let will genarly free them up
