Engine Performance problem
1991 Chevy Corvette V8 Two Wheel Drive Manual 58,500 miles
Just got this car this spring - I changed all filters and fluids and new spark plugs. Every thing ran great for first 500 miles, but the last 2 or 3 times I took it out for a nice Sunday drive and a problem occurred.
Car starts and runs fine when engine is cold.
After engine gets to operating temperature, I have the follwing problems:
a) Hesitates and stumbles during acceleration
b) Idle increases to almost 2,000 rpm
c) During steady cruise speed 40 -50 mph, engine misses - not enough to change vehicle speed but you can still feel it.
have the same problem?
