elmyko Posted March 1, 2014 Share Posted March 1, 2014 I have a 90 subaru loyale and has a rough idle while sitting which sometimes idles fine and other time just get rough jumping around 600-1000. I have replaced timing belts, spark plugs, rotor and cap, IAC, and fuel filter. Wondering if anyone has any ideas? Link to comment Share on other sites More sharing options...
Dinky26 Posted March 1, 2014 Share Posted March 1, 2014 Fuel injected or carbureted? Link to comment Share on other sites More sharing options...
suprjohn Posted March 1, 2014 Share Posted March 1, 2014 My '89 DL wagon has similar symptoms. When I get the interior sorted, I'm going to look for vacuum leaks. John Link to comment Share on other sites More sharing options...

MR_Loyale Posted March 1, 2014 Share Posted March 1, 2014 Check for vacuum leaks around hoses and the intake gasket. With mine I have taken the strategy of just replacing the 20 yr old vacuum hoses on principle. They are rubber and will deteriorate over time. They are not expensive and saves me having to chase down piddly little leaks in hoses that cost 75 cents to replace. Link to comment Share on other sites More sharing options...
