fuel injectors?, fuel pressure? low compression? even vacum leaks can cause misfires,

I have a corolla and had #4 cylinder misfire also diagnosed at autozone. After changing the spark plugs, problem persisted, along with the same error code, so they recommended changing the spark plug wires, and that is what fixed it. I would have changed the rotor cap too, but was low on dough. Glad that was not the problem.

OK IS THERE IS ACTUALLY A mis-FIRE THIS VEHICLE SHOULD BE SHAKING DURING IDLE AND ACCELERATION IF IT IS, here is what you do get a noid light this used to check injector pulse. This vehicle will set a misfire code if injector is not functioning efficiently or bad. A noid light is like a test light bulb can be bought at almost any auto store.SART UP VEHICLE AND DISCONNECT THE INJECTOR WIRE TO THE CYLINDER THAT'S mis-FIRING AND CONNECT noid LIKE TO ELECTRICAL PLUG. DO THIS ONE CYLINDER AT A TIME. The nod light should have a steady flickering light/consistent pattern of flickering. If there is Gap/irratic flickering or no flickering BINGO you have found your problem. NO FLICKERING= bad/broken injector wire if not broken BAD COMPUTER/ECU. IF THE FLICKERING IS CONSISTENT /GOOD = BAD INJECTOR..replace injector and solve the misfire problem. However is all the components tested are ALL GOOD. Then the only other SOURCE for a mis-fire is the camshaft sensor that provides reference for injector pulse and the crankshaft sensor provide reference for Spark pulse. JUST ON A LAST NOTE: make sure all oils are getting electrical power to them. Good Luck I know this is alot of info at once. Contact me if you need more help. Thanks fr using FIX YA
