Since I have my Mustang I always get backfire in the exhaust when decelerating. I know it can be a timing problem but what else ? It did it when I had the 2 barrel carburetor (and at that time the car seemed properly tuned), now I have a Holley 4 barrel and it's the same. What do you suggest to check ?
