After driving the car under normal conditions and then the engine heats up to normal operating temperature. If I stop for a few minutes, put the car in park and come back, say 2-3 minutes later the temp gauge is moving up towards the hot mark. The coolant resevoir is full, it also seems that the thermostat is not opening (stuck) cause I don't think the coolant is circulating properly.
Unfortunately it is acting like it did about a year ago when the head gasket was getting ready to blow. Oh BTW it has around 109,000 miles on it.
There is no coolant leakage on the ground anyway to my knowledge. It also started bucking/skipping this morning and the "service engine soon" light started flashing.
Any ideas what may be going on? Thanks.
