Hello, first of all, I would like to thank you for talking the time to read my message. Okay, I got my 2000 Ford F-150 as an 18th birthday present from my dad. I have had it for about 3 months now. About two weeks ago, I was coming down my street and my engine stalled suddenly. Thinking nothing of it, I started it back up and drove home. The next day a misfire appeared but the MIL didn't come on. I took it that same day to the shop at my school and replaced all eight spark plugs and wiped the coils with a rag. This worked for about 3 days. Then I got a misfire in cylinder 8. I continued to drive it for a couple days. Im not going to drive it anymore until fixed because I now have a mis on cylinders 8, 5, and 3. And a blinking MIL. My funds are limited so I cannot afford to replace parts that work fine. So please, can you give me some advice here. I have no idea what the problem could be. Nobody knows. Im begging you, help me out here. Thank you.

Just as a general question, have you run it through a good size puddle of water? The engine has coil-on-plug design (as you are aware). They have a reputation for going bad. If you know for certain which cylinders are missing, you could try switching the coils to cylinders that are not missing. If the miss follows the coils, replace the coils. It is also not uncommon for multiple coils to go bad at the same time, especially if they have had water on them or been cleaned with engine cleaner containing silicone. I have had to replace as many as six because the engine went through a detail shop that used silicone-based cleaners for the engine (a real bad idea for C.O.P. Design engines). Hope this helps.
