I took it to my mechanic when the problem first arose and he pulled the codes. He wrote them down, but I don't remember them right now. In an earlier post I wrote in this thread I listed a description of the codes I could remember. Maybe I'll replace the coil packs next weekend?glowstang93 said:I never disconnected my battery when replacing mine, so I doubt that is your problem. When I had the same problem, I replaced the coil packs also and so far so good. Coil packs were $60 each from O'Reilly's . Did you ever have the codes pulled or take it to a shop?
Where are they? Can I get a picture anyone? And what do I need to get to see if they have spark or not?Stinger said:Swap coil locations (front to back, back to front) and see if the dead spark plugs follow the coils (switch sides) or not. If the loss of spark follows one of the coils, it is bad, if not...the coils are still good.

Didn't get a bill yet.
Oh and they put the tires on the Ponies! Pics tomorrow!
Not sure on either account. My Mom talked to him and all she knew was it was the coil pack(s), O2 sensor and a melted wiring harness.glowstang93 said:So did he replace one or both coil packs? Which wiring harness was melted? Just curious. Later.
He replaced one ignition coil ($96.25). The wiring from the O2 sensor to the computer fell on the header and melted ($77 for the sensor and $28 for the wiring).glowstang93 said:So did he replace one or both coil packs? Which wiring harness was melted? Just curious. Later.
My 92 2.3L is doing the same thing. The tach is running at half the reading it should be, the check engine light comes on and stays on, but otherwise the car runs fine.
I pulled the plug on the front coil pack and the car ran worse. I pulled the plug on the rear coil pack and there was no change. Pulling either coil pack plug resulted in the tach reading zero. I am guessing something is wrong with the rear coil pack but I differ to your wisdom and advice.
Question:
Will coil packs from a 4.6 also work? I think my chances of finding an old 4.6 Crown Victoria in the junkyard might be good as well.
Question:
Would a younger Ranger also use the same ignition module?
Question:
I noticed the rusted and damaged remains of some sort of heat shield, mounted on the exhaust manifold, below the coil packs. Something tells me this is a contributing factor to coil pack failure in the rear pack. Anyone find ways to insulate coil packs or repair the heat shield?
