Hello Scotty and all!
I recently found your YouTube channel, and I am glad I did. I am loving your videos. :)
I do have a question...
I only recently bought my first vehicle, a 1999 F150 4.6 v8 (~146k miles). Unfortunately it has started running rough over the past couple months. At the moment, the issues I am having are:
- When I hit between 40-45mph, with overdrive on, it starts to buck and doesn't want to accelerate. With overdrive off, it doesn't completely go away, but it runs much better.
- I have 2 misfires atm, along with codes for the o2 sensors. The o2 sensors, though, I believe is due to the previous owner having the catalytic converters removed.
- It seems that at odd times the transmission isn't shifting properly. It will either shift late or be a hard shift.
- With the A/C on, it almost becomes impossible to drive, seems to lose a lot of power.
I had the coil packs and wires changed about 6 months ago. At the time, I was told the spark plugs were fine. I had the misfires going into this, so that didn't resolve it. So I am wondering if the spark plugs did actually need changed.
A few people I spoke with seem to think that changing the plugs will resolve most of my issues, but I am not so sure. Then again, I don't know much about these kinds of things.
Any input or advice would be greatly appreciated!
