I have had a problem with the engine stalling when outside temps exceeds 85 degrees and the a/c is on. The problem occurs after taveling at highway speeds and the cluch is depressed and the engine is allowed to idle. The engine intermittenly will immediately stall. This causes a partial loss of braking and power steering. This happens about once a day when temps are over 85. The problem has been happening since 1997. The dealer has looked at the car 4 times and has tried fixing the a/c to resolve the problem. They say the I need to bring the car in while it is stalling?.

The check engine light comes on and stays on. Upon slowing down while driving at highway speeds the vehicle jerks forward. Dealership replaced the egr valve and sensor 3 times in an attempt to correct the problem, but failed to do so.
