Check the timing on your vehicle ,but there's more on why your getting a misfire
CHECK THE IGNITION SWITCH,,, THEY HAVE A HABIT OF GOING BAD
have you replaced and or tested both coils? are you getting no spark on the intake and the exaust sides?
Assuming it is getting fuel and you have no spark, replace the ignition module.
I would definitely change the gas and probably the oil first. Check for spark and fuel getting to the cylinders.
I've replaced ignition switch, and starter solenoid, checked fuses, and battery, but I don't seem to be getting any electrical through to start the engine. I can jump everything and get the engine to turn over but not start.
it might be a broken motor mount. there are two mounts located towards the bottom of the left and right side of the engine make sure you are getting spark to all cylinders. (check for Misfiring)
Check to see if you are getting spark (coil) and fuel
try to get a new ignition rotor
You may have a faulty ignition switch. The ignition switch feeds the fuel pump.
Coil, injector, internal engine....
probably timing or valves. cylinders getting too hot which is igniting fuel that is left after it has been turned off
