my 2.2 CL 5 spd is hesitating and stuttering, usually after it reaches normal operating temp and is worst on a humid day. My brother-in-law mechanic just tuned up the car this last spring (plugs, wires, ignition coil, cap, fuel filter). He tested the fuel pump, vacuum pressure( through the catalytic converter), and fuel injectors, everything checked out! the speedometer is also intermitent and it seems that when the speedometer is out, the car runs fine, and when the speedometer kicks back in, it will start hesitating. Does anyone know what this could be from???
