There are three kinds of gasoline engine misfire scenarios, first there is the "under load" misfire and there is the "at engine idle" misfire, and finally there is misfire continuously. All engine misfires exist because one of three things has occurred. First, a cylinder has lost compression, a cylinder needs a certain amount of compression to operate correctly. Second, the ignition system has failed or is failing intermittently, spark is needed at the time of compression to ignite the fuel air mixture. Third, the fuel air mixture is incorrect, proper mixture is needed for the ignition system to ignite fuel properly. If any of these conditions occur in the engine, the engine will misfire.
1. Low or no compression can be caused by
a. burned or leaking intake or exhaust valves
b. worn or broken piston or piston rings
c. worn out camshaft
d. wrong weight motor oil was installed holding the cam followers from adjusting
e. broken valve spring
f. failed head gasket.
2. Ignition system has failed or is failing
a. spark plug has fouled or is worn out
b. ignition coil
c. spark plug wires have shorted
e. engine control module coil driver has failed
3. Fuel/Air Mixture is incorrect
a. vacuum leak at the intake manifold
b. fuel injector has failed
c. EGR valve is stuck open
d. mass air flow sensor has failed
e. oxygen sensor has failed
f. air intake boot is cracked
1. fuel injector has failed or is failing
2. spark plug wire has shorted
3. spark plug is worn out or is cracked
4. ignition coil has failed is failing
Testing a coil on the car is pretty easy. No special tools are required. Just remember to be careful, the amount of electricity generated by your ignition system can be dangerous. If your coil is already off the car, or if you would like a more specific data-driven test, you can bench test your coil. To set up the test, remove one spark plug wire from its plug, then remove the spark plug using a spark plug socket. Next put the spark plug back into the spark plug wire. Be careful not to let anything drop into the empty spark plug hole -- very bad.

Hi, my first recommendation would be to take the plugs out and visually inspect each one and check to make sure they are properly gapped, if they look fouled at all i would replace them without hesitation. try throwing a set of NGK plugs in the car to fix the misfires. other than that you may want to look at the wires. good luck joe

I HAVE A COROLLA 1999 MODEL. IT IS MISFIRING. I CHANGED THE PLUGS AND CHECK ATHE INJECTORS. NOW I DONT KNOW WHAT TO DO BECAUSE THE ENGINE STILL VIBRATES AND THE CHECK LIGHT IS ON

theres a possibility that the #2 fuel injector is clogged up. go to any auto parts store and tell them your problem, they should have a fix. unless the injector is bad. good-day!! are you sure #2 wire is ok! You probably need to clean out the MAF/sensor as well as throw in some injector cleaner.
