MISFIRE ON NUMBER 3 CYLINDER STILL!

Chevrolet Corsica

Ok, I am back, Corsica 96 2.2 automatic, replaced plugs, wires, coils, ignition module, map sensor, coolant sensor, fuel injector on number three, pressure regulator, and I still have misfire on number 3 when cold engine sometimes. HELP? And question can crank sensor cause misfire on #3 at times? Help please, its driviing my husband crazy? Ha!

First things first. Three things that control engines. Fuel, Spark and COMPRESSION do a compression test!
