2001 F-150 Coilpacks

[KickAssFlash]

The coilpacks on my '01 are going out. I had two of them replaced a year ago, but I have enough time to tackle it myself now. How hard of a job is it?

Very easy. i have about 20 factory ford coils. $15 each.

burn out coils much?

Don't drop the bolts under the intake, and I would be sure to use Ford coils, not aftermarket

they are a cake walk.

[OhMannClint]

easy yes

[KickAssFlash]

How do I figure out which one is the problem? Or do you normally replace them all at once?

To find the bad one, you need to either swap in a good one until the stumble goes away, or find a scan tool that will read any codes that have been thrown. I ended up taking it to the dealer I bought it from, and while in the service lane, they plugged in their $2K scanner, and we could see the plug that wasn't firing. Glad we had their scanner, because I hadn't thown any codes.

Also, be careful moving the coolant lines over the coils on the passenger side. If they leaking later, they will fry the coils under there. Those are also the hardest to remove because of the coolant lines. The others are a cake walk!

Wheres the new job?

I went to Advance Auto Parts and had the code pulled...apparently it was the bank 2 sensor 2 oxygen sensor. Hopefully this fixes it.

[KickAssFlash]

Gay. It still has a hesitation under acceleration, but it's not as bad as it was. The only code that came up was the 02 sensor when I took it in. The check engine light is still on, though. Does the engine management system automatically clear whatever is fixed or does it stay on?

I guess I should also make sure I replaced the right sensor. The code came up as bank 2, sensor 2. This is the passenger side, furthest rear sensor, correct?

You'll have to clear the codes manually. I have a code scanner here if you need to borrow it.

One thing, they won't always throw codes when they are first going bad. On my old truck I went through this a few times before I made sure to put plenty of dielectric (sp) at the base of the plug boot(to seal out any moisture) on the coil. The easiest way I found to figure out the problem was to put the truck in gear and unplug one coil at a time. Not the safest way but you could have a buddy in the truck with it in gear and have his foot on the brakes while doing this. The one that didn't make any difference in idle quality was the bad one.

If you have access to a scan tool find mode 6. On a genesis it's in the obd II section, not the OEM section. It will show each cylinder and how many misfires it's had. There's nothing wrong with aftermarket coil packs, as long as they are good quality coil packs. My truck had an aftermarket coil put in at 75,000 miles and it's got 145,000 on it now. Find a 1/4" drive, 7mm swivel socket. That will be your friend on this job. Also, you might as well put plugs in it if they haven't been done in a while. They really aren't bad to do.

i have 2 coil packs that i no longer need, both work fine. i also have a scanner that can clear your code.

let me know, only night i can possibly help you out would be on tuesday.
