Re: 95 zr-1 lean pop
Does the motor have any mods?
If so, do you have an updated PROM? I know first hand that aftermarket exhausts will cause popping on deceleration. In my case it's the Flowmaster cat back system. But I suspect all the other aftermarket systems will do the same. An updated PROM from Haibec cured my popping. 'Crabs
