: 1994 Concourse stuttering

02-09-06, 10:34 AM
Help--My concourse has started to stutter when going up a hill or when I barely push down on the accelerator. It kind of hesitates to speed up, but when I push down all the way it takes off like a bat out of hell. My mechanic has checked the 4 coils and the inginition wires and found them to be OK.

Any other suggestions? My gas mileage has remained approx. the same.

Check the fuel injector, FI fuse, or it could be a clogged CAT.

Replace the wires. Stick with A/C Delco.
