Question about 1985 Chevrolet Corvette
The car idles fine and is ok when the car is cold as it gets hot and you step on the gas the car chokes out and sputters really bad. I have done a tune up changed the fuel pump and filter and still it has the problem.
CHECK THE VOLTAGE ON THE TPS, IT SHOULD BE .45 TO .54. GO WITH THE .54 AS THE MOTOR NEEDS TO BE RICHER DUE TO THE ALCOHOL IN THE FUEL. YES THERE IS AL IN YOUR FUEL. I SET MINE TO .57 AND THE PROBLEM WAS SOLVED. NO MORE STUMBLE. ALSO THE CHANGE IN FUEL REALY DOES NICE THINGS TO THESE CARS. CHECK THE EGR VALVE TO SEE IF IT IS STUCK.
