I have a 2000 Mustang GT with 152,000 miles and a manual tranny. I am getting a surge and buck when accelerating so I checked my COPs and there was coolant on the ones on the drivers side. The passenger side COPs are perfectly dry. I looked in the holes of the driver side and found puddles of coolant around the plugs. I replaced my intake manifold about 5 months ago hoping to fix this problem. Ive had this problem before. I did everything right with the gaskets and all! Still coolant is getting in there, unfortunately. My guess is a bad head gasket. If you guys could give me any thoughts or any info. on a head gasket replacement that would be great!
