964 with Engine bucking bronco problem
Has anyone experienced a problem with their 964 having engine bucking issues when cold. I live at 3100 ft and when I come down the mountain I am not gassing it. When I get on flat land, the car will buck as if it is trying to get enough fuel to run correctly. Often it dies and when so, I shut of and crank up and it sometimes runs correctly and sometimes it runs a short distance and does the same thing again. After several complete shutdowns and start ups, it runs great. I replaced the DME relay and fuel pump based on the Porsche mechanics suggestions. The car has 116,000 miles and is well maintained. Someone else suggested I try replacing the cylinder head temperature sensor. Before I go this route, I would like additional advice because I but do not want replace components as we search for the problem.
