i just put a overhaul kit on my car mainly cuz i blew a head gasket and didnt have the money for a complete rebuild, but now when i i drive the car to say 4k rpms and let off the gas the exhaust pops.
and when i accelerate the car acts like somthing holding it back then it pops a coulpe times and its fine. when i race my car its fine...any ideas?

timing could be off...check that and your fuel pressure. those would be the first things id check

actualy i never had one till now........first time i started my car after installing the overhaul kit, the lower intake gasket shifted and all the coolant went though the cylinders....could the spark plugs be bad? plus could a bad cap and rotor do this aswell?
