missfiring

I drive a 1988 2.3 Turbo Coupe. While driving, or idleing, it miss fires. I checked the spark plug wires and they are brand new. I just bought a new distributor button for it, and its got a V8 distributor on it. The button was cracked, so I replaced it hoping it'd clear it up, but it didnt. Does anyone know what else it could be? Im thinking its the distributor cap, but its in good condition.

Re: missfiring

get any better at higher rpm? those have a fuel injector for each cylinder right? if so it could be fuel related(plugged injector) or electrical in relation to the fuel system.

Re: missfiring

Check to make sure the injectors are receiving a signal also. You can do this with a 194 bulb.

MOVED.......... to Thunderbird Discussion.........

Re: missfiring

If this car has individual injectors, simply remove the connector from the injector and take a "194" bulb (get one at parts store) and on the bottom of the bulb pull the wires out straight.
Plug the bulb into the injector connector and crank it over. The bulb should "pulse" letting you know that the electrical part of the injector is getting a signal.

does'nt take much to pick up a miss on the exhaust side if valve is burnt, hopefully it something easy if you do have aa low cylinder do a lead down test. thats a little more indepth but its better than pulling the head!!if that don't do it start this
