My Galant is having the above problem. I am providing some details (below) related to the problem:
a) Check engine light was on. I took to a repair shop. The code was non specific. They did engine tune-up. The problem was not fixed.
b) I took to Mitsubishi. They could not find any specific problem. They recommended changing CAM sensor. After replacement, problem still remains.
c) Recently the car does’nt want to start. Check engine light is gone. Reving is still there at start and during stops.
d) I have noticed some of the coolant splashing out to the adjacent tubing during driving. The coolant chamber is empty. But the engine heating indicator is in the middle.
Please help me with a expert solution. Thanks.
