poor fuel econmy???
HI EVERYONE.
IM WRITING FROM CHILE.
I HAVE A 89 IROC WITH 5,7 TPI SINCE JANUARY. THE CAR IS RUNNING 8 TO 9 MILES PER GALLON OF FUEL. DO YOU THINK ITS EXCESIVE?? I THINK SO BECAUSE I HAVE BEEN DRIVING V8 CHEVYS FOR A LONG TIME AND HAVE SEEN THAT V8S WITH CARBURETOR RUN 12 TO 13 MILES PER GALLON.
I WOULD APPRECIATE YOUR ANSWERS.

That's pretty bad. Check the tune to start with. Plugs, wires, cap, rotor and timing. Check the fuel pressure regulator, pull the vacuum line off of it while the car is running and make sure gas isn't running out it. The regulator can rupture and push gas through the vacuum hose up into the intake at a fairly good rate.
