Does it bacfire thru the intake or exhaust? Does it backfire once then run ok? Is this only cold or warm too? Possible vacuum leaks, old lines cracked?If you can fedl around the rubber hoses whild it's running and listen flr an engine change or a different whistle start that is where your leak is.

Thanks guys! had compression test done. all seems to be okay. it idles without backfire and don't backfire til it gets to 2000 rpms, then reves good up to 3000 rpms and then it "pop" "pop" "pops" reves up to 4000 rpms then "pop" "pop" "pop". will check to see if it thru intake or exhaust and if it does it cold or warm . will also check vacuum leak and lines.
