    I have a 98 dodge with a 318. It seems to idle fine in park or neutral but, when it is gear the engine seems to misfire every couple of seconds, this happens usually at a stop light when the engine is warm.

    I have same propblem with my 318, it missfires every other second. Thought it my be the fuel injector, so i put a can of cleaner in the tank and it cleared up considerably but still misses sometimes.

Make sure none of your wires have touched your exhaust manifold.... if those wires burn then the metal on metal of wires causes it to misfire.

I have an Acura tl 98 its missing fire #4 what could be?


Misfires are caused by fuel delivery problems, injectors or too rich or weak. Spark issues, coil, wires, spark plugs or the cap and roter.
I could also be a loss of compression. First thing to check is the easiest... spark plugs, spark and cap and roter. Also the cheapest.

Misfire on cyclinder


I would check the fuel injector on number 2 cylinder. If the injecter is dirty or not functioning properly it may give you the symptom of an ignition misfire.

Just a note, if this is an unaltered system, it should contain a sequential fuel injection system, which does not use a conventional throttle body. It uses a spider system instead, which is much different than the pre 1996 models.
