I have a 96 Lumina with the 3.1 engine. Recently I had the PVC valve replaced and the radiator flushed and refilled. After doing this I developed a radiator fluid leak. Also when the car gets up to temperature it acts almost as if it has a governor on the throttle. It will rev up to a certain level and then surge back and forth from that rpm to a little lower. I have read the other issues people have had with intake gaskets being the cause of the fluid leak but would that also cause the loss of power and higher RPMs? Any advice would be appreciated. I already got a quote on the intake gasket and they want $550 so I need to know. I did put in some stop leak and the leak seems to have gone away but still having the problem with the RPMs.
have the same problem?
