Tip & How-To about Chevrolet Camaro
One way to find an engine miss, start the vehicle, and with a pair of leather gloves, (so you don't get a jolt and you might want to remove each wire boot and reinstall with the motor not running, this will help ease removal of the spark plug wires when the motor's running, also spraying some WD-40 and twisting the spark plug wire boots will help in removal of the spark plug wire). You'll want remove 1 spark plug at a time, if the engine bogs down or idle drops, put the wire back on, go to the next spark plug wire, until you get to the spark plug wire that has no effect on the running of the motor when you remove the spark plug wire from the plug, that is the cylinder that has a problem. The problem causing this could be the spark plug (wrong spark plug gap), a bad spark plug wire, the terminal on the distributor cap, or even an internal engine problems i.e, intake or exhaust valves, bent pushrods, broken or weak valve springs, or bad compression rings on the piston. This will help you narrow it down to what cylinder it is. If removing all of them doesn't make much difference, there could be a vacuum leak, caused by a broken or disconnected vacuum hose or fuel delivery problems, plugged fuel filter, low fuel pressure, or a bad fuel pressure regulator.
