Question about Cars & Trucks
First, quit begging, why did you buy this piece of s--- ? do you have a licence , donot drive this vehicle until its fixed, its dying, your kickingdead horse dude stop it, now. don't know if this can be fixed. now, timing is way out, lets keep it simple, you need the following : spark plug wires, the right spark plugs, if you have a distributor of some sort, get it a new cap and rotor, all stock items, not aftermarket . when was the last time fuel filter was changed, do it. find out where the timing needs to be, repair manual for this car by haynes . you need it. after completing all work, timimg must be checked, and set, need timing light, inductive type best, make sure plug wires are on the right spark plugs and in the distributor @ right location, see repair manual. place timing light around #1 spark plug, and also attached to battery terminals red is +, black is - , negative, knowing the timing, start engine, keep timing light wires away from fan, etc., have distributor hold down bolt loosened so you can turn it while you point the timing light towards crank damper to see timing mark, (marked w/ chalk ) timing light will flash quikly turn distributor until the correct timing is achieved, (see repair manual) for correct location of timing, when you reach this position, tighten down distributor hold down bolt, now your timing is set. Is engine running better ? NOTE: some engines need to unplug something before timing is set, (see repair manual) like the throttle position sensor, yours may be somthing else, find out which one. (repair manual) its important ! make sure all vacumn lines are in proper locations, its important, now man up and prove to me that you can do it, this can change your life, 321 goooooooooooooooooooooooooo!!!!!!!!!!!!!!!!!!!!!!!!!

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.
