popping noise

I have a 86 buick century with a 2.5 ltr eng. There seems to be a loud pop or snapping noise coming from around the fuel injector. This pop or snap sounds almost like an arcing wire but I checked all the plug wires and they don't appear to be the culprit. Any ideas or help would be great.

Any exhaust or vacuum leaks? First place to start.

no vacume leaks and not 100% positive on the exhaust leak but fairly certain there isn't one.

the 2.5L engines were and are notorious for cracking the thin cast iron exhaust manifolds.
