1993 Chevy Corvette V8 Two Wheel Drive Automatic 85000 miles
Hello, My 93 Corvette generally runs very well. Lots of power and nice take off. The engine does miss between 45 and 50 mph. I notice if I am accelerating hard it goes right thru 45 and 50 just fine but it does not like to go down the road between 45 and 50. Seems to get worse if I use a fuel other than a 92 octain. Also I notice if I drop the automatice transmision down to drive instead of the overdrive, and increase the rpm, it does not miss. Could it be a problem with vaccuum advance?
have the same problem?
