Asked by snessman215 Sep 16, 2011 at 08:43 AM about the 1999 Mitsubishi Eclipse GS

Question type: Maintenance & Repair

A.T. 2.0 non turbo. car overheated. pulled head n had it milled 0.009ths back to level. reinstalled head wi 0.010 thicker head gasket.
now car will idle perfect at first but anything above idle (well, above ~2300 rpm)it starts to miss. once it starts to warm up it struggles to idle. miss gets worse. plugs show rich condition. replaced coil, plugs, coolant sensor, MAP, and O2. also loosened the exaust in front of Cat in case it was plugged up. nothing has made any diff. compression is running 145 - 150 in all cylinders. not throwing codes since replacing MAP and coolant sense. anyone have any ideas besides Dynamite?

Stick a for sale sign on it. I have a 98 GS and had the exact same issue. Overheating, cracked blocked, new coil, plugs, wire, censors, radiator, and ECM. 5 days later, new blocked cracked. Common issue with these cars. There money pits. Trading mine in tommorrow. Good luck.
