My 75 TR6 with 69 engine has recently (the past 2-3 months) developed a tinny
sounding backfire upon deceleration, either when downshifting or when dropping
back down from a stopped fast idle. Can't seem to find the problem. The car
runs at very low, very rough idle and gets lousy gas mileage, although this has
occurred only since the tinny backfire began. It has a Crane XR 700 electronic
ignition and high output sports coil installed about 10 years ago. I always
keep plugs and wires maintained and gapped.
Does anyone have any suggestions about the cause and the solution?
