I PLUGGED THE OBD2 MODULE AND IT THREW A P303 CODE WHICH I LOOKED UP AND SAW THAT IT WAS A CYLINDER THREE MISFIRE, I WENT DOWN TO AUTOZONE BOUGHT SPARK PLUGS AND WIRES, I CHANGED THEM AND STILL I HAD THE ENGINE CYLINDER THREE MISFIRE. IM THINKING MAYBE THE DISTRIBUTOR CAP BUT IM NOT SURE WHAT TO DO OR THINK IF YOU COULD PLEASE HELP ME OUT WITH THIS PROBLEM I WOULD APPRECIATE IT.

i dont think its the distributor cap, one thing to check, make sure no two spark plug wires that are right next to eachother in the firing order are running parrallel or youll get crossfire.

next step is to check for spark on that cylinder and compare it with the rest, if its good then the ignition isnt to blame.

check the compression and fuel in that cylinder.
