My 91 RS V6 3.1 liter misfires when it gets fully warmed up, but not when its cool. This has been happening for HITHERE while now. HITHERE replaced the passaner side exhaust manifold and EGR, which was leaking. Is there anyone out there that knows some secret to this engine??? HITHERE am an automotive technician, and HITHERE've been stumped by this one for HITHERE while. The car has great compression, and lots of new parts. HITHERE just want to fix this misfire problem so HITHERE can sell the car. Thanks Adam
