Misfire Help Please...

You folks have gotten me out of situations before. On the way to the beach, where I am now, I got a check engine light and misfire under load. Fortunately, I have a code scanner but only basic tools here and no manual. My scanner gets a consistant misfire on cylinder #3. By the way, '96 Aerostar with 3.0L with 105,000 miles.

I changed the plugs and ignition wires here but get the same error. I switched a few of the plugs and wires around but got the same error. The plugs looked normal. I do have a Ford dealer ship nearby and was planning on getting a distributor cap in the morning.

Any suggestions anyone has would be greatly appreciated. As I said, I have a socket set, basic hand tools, and a code reader here.

Thanks!

Misfire Help Please...

hi dillon77
I am having the same problem with my 96 windstar it has a 3.8l and I have done the same thing plugs, wires, cleaned the upper and lower intake, checked sensors, I am running out of options I think the only thing left is the coil pack in fact I just called about one tonight and they are $70 at autozone oh mine is on the #2 plug. if you do happen to find something different please let me know. I am sorry I couldn't help you out more though. I did just drive back and forth to indiana though about 7hours on the road and the van did ok and I suppose it would have made it further if needed I think you would be ok driving it where you need to without too much trouble.
again sorry I couldn't help.
Ben

The other item you should check is your fuel injector ,if one of them is faulty it will seem like a misfire
I am aware of them starting to work intermitently

hope this helps

You may want to switch the plug and wire with another cylinder and see if the problem follows. This is what I've done and have not had the problem the last few days. I was hoping to narrow it down. It'll probably happen when we hit the highway for home.

If I still get the problem with the same cylinder, I'll probably look to the coil pack/distributor cap. Then I'll look to the injector for that cylinder. I did pour in a bottle of Sea Foam, the best cleaner the parts store here said they had, into the fuel tank for the time being.

I appreciate any other suggestions.
