got my new goodrwench crate motor in. this is a stock engine with just edelbrock performer intake and edelbrocks qjet. has headers and dual flowmasters.

now the problem, say im going 75mpg or faster on the freeways and i let off the gas pedal to slow down i will hear multiple little back fires through the exhaust. theyre not loud at all, pretty soft.

im sure this relates to the carb since it is not new. is it just running to rich? and ideas?
