86 thunderbird 5.0 HO misfire in #2

Asked by freakandfan Jul 17, 2014 at 12:38 AM about the Ford Mustang

Question type: Maintenance & Repair

i have a misfire in cylinder # 2 at idle and low rpm. i have replaced the spark plugs and
checked the gaps on them (.045), changed the injector and o-rings, wires, coil,
distributor cap and rotor, upper manifold gasket, throttle body and EGR gaskets,
checked and replaced almost all vacuum lines, purge valve and still having the
problem. the misfire is followed up by a ping in the exhaust and only does it at idle and
low rpms. if i remove the spark plug wire for cylinder #2 the ping in the exhaust goes
away and the car seems to be running smoothly like there was never a miss at all.
when i removed the EGR there seems to be coolant in it as well.

1 Answer

I timed it last night and it seemed to help alot then it started to act up again and now there is no power in any gear and it will spit and sputter and the car will drop really low in rpms and cut out
