IDLE TOO HIGH
i HAVE A 93 T-BIRD WITH THE 302 HO. IT IDLES WAY TO HIGH. IT WILL RUN OUT AT 40 MPH WITHOUT TOUCHING THE GAS. I HAD IT ON A COMPUTR SCAN 3 TIMES IT SAYS NOTHING IS WRONG? IT WILL OVERHEAT IN ABOUT 15 MIN. IF LEFT IDLEING. THE MECHANIC PULLED SOMETHING THAT IS SUPPOSED TO RETARD THE TIMING BUT IT NEVER CHANGED. ANY HELP WOULD BE APPRECIATED.
THANKS VINCE.
