I own a 1998 F250 (F150 7700) 4x4 with the sift on the fly ****. It has 194,900 miles on it. The other day it had a misfire and my basic OBD reader stated misfire. I wanted to see witch cylinder but after a day of driving can’t duplicate it to read it at a local auto parts store. So don’t know witch cylinder. I would like to do an overhaul on the truck so it can give last me until 250,000. I have the opportunity to leave my truck at a friend’s garage to do the work and I buy the parts. I wanted to ask members what they would replace on the engine and transmission without a whole engine rebuilt and transmission rebuilt and had around $1500 to spend?

I would change:
1. Plugs
2. Wires
3. Coil Pack
4. Vacuum lines
5. ???

Do you have a misfire code for a specific cylinder? Myself, I would troubleshoot the problem versus replacing everything because the parts you listed may not solve your problem.

Thank you for the reply.
I thought I posted the question on the correct link. Sorry about that.
I've driven the truck for two days this week and the misfire has not returned so I can't get a cylinder code.
I will ask a moderator if he can move the post.

Thank you again.
