I just replaced the plugs and wires on my 01 Explorer and now the check engine light is on (blinking now, solid at first), very little power no matter how far gas pedal pushed, and there is a funny smell, almost like something is getting heated. I can't find any parts rubbing, and I've double checked each plug and wire for proper seating, tightness, etc. I'm at a loss. Any help is appreciated.
need information on engine... did you put wires on correct plugs??
Lots of folk get this wrong
What is the firing order for a Ford explorer 4.0L v6?

--------------------------------------------------------------
The engine cylinders / spark plugs are numbered :
passenger side of engine , front to rear , 1 , 2 , 3
drivers side of engine , front to rear 4 , 5 , 6

The COIL PACK TOWERS are numbered :

front
I'm certain I have the wires on correctly. I did them one at a time, but I'm gonna double check (again!) anyway. Disconnected the battery before changing the plugs and wires, NO cel light on before, and the smell is in the bay, but it may be coming from the anti-seize compound I put on the plugs. Never used it before, but I read that it can cause fumes for awhile as it settles in.
I talked to a Ford tech, and he told me it was a misfire. Apparently, the blinking check engine light means a misfire in this instance. I guess I'll be up early tomorrow chasing it down.
Wouldn't you know it? After thinking all night about getting to that last plug in the back, the problem solved itself. I didn't do anything except pull the negative battery cable again and let it sit for about 8 hours (apparently the 2 hours it was off while I was changing the plugs wasn't enough). When I fired it up again, the check engine light was off, and it was purring like a newborn kitten. Anyway, thanks for all the advice.
I'll bet you have a wire or two that are not properly seated at one of the ends, either the spark plug or the coil. For whatever reason it is making contact currently, but after a good pothole the misfire will be back. Getting the stored/history codes read would give you a wire or two to start with.
I did check the wires again. They were all nice and tight, and none were crossed. Where I live in California, a loose wire wouldn't last 50 yards. I've never had this kind of issue before when changing plugs. I just wonder how long I was supposed to allow the computer to reset itself. Ah well, I'll worry about it in another 100k miles.
