Weird new problem

Hey guys,

ever since having the valve cover gasket done, my radiator light has been coming on at start up. Needless to say I checked the level and it was fine. The car ran OK so I wasn't worried about it.

Recently, the car has developed a studder/hesitation under load. If I drive gently no symptoms but If I squeeze into the throttle its as if it is on 3 cyl.

Then today, it is very hot so I turned on the A/C. Worked great but when I came to a red light the a/c went off, and the overheating light came on. (different from the radiator light). When the light turn green, I accelerated gently, the light went off and the a/c came back on. Happened at the next light, I brought the revs up but again the a/c didn't come back on until the car started moving.


Haven't pulled any codes yet, just wondering if you guys have any ideas where I should start.

By pulling codes. When is the last time the cooling system was updated - have you bled the system? Clean the vanos solenoids, maf and basically do everything that is cheap and free - then we move from there.
