How to change coil packs
I just got this 1999 F150 w/ 4.2l v6 automatic from an auction with 178 k miles on it -- yikes! Anhyhoo, on the drive home, it ran horribly. Symptoms are as follows:
Shuddering/sputtering/lack of power at high speed and on take off, better with OD off (at high speeds)
Smokes when sputtering
I have read that there are a number of issues that could cause this, but it sounds like coil packs/plugs would be a good place to start. So, let's say it is coil pack(s), then I have the following questions:
1. What codes should I expect (did not have time to scan today)
2. How do you replace the coil packs and plugs (I am neophyte when it comes to this stuff).
3. Let's say it's the torque converter, is that something I can do myself without a lift?
I looked in the how-to section and could not find anything on replacing the COPS. Thanx in advance for the help.
