Check your timing

 

As Polaradude says, check your timing. Also, check for vacuum leaks, and exhaust leaks. Sometimes a little fresh air is drawn in through an exhaust leak, where it can help unburned fuel ignite, causing popping.

 

k ill try tht thanks for all ur help

 

just curious is it a loud pop or a low muffled type of pop?
