    Question 99 F-150 Lariat 5.4 skipping

    Hey guys, my F-150 started skipping/missing on the way home from work tonight. I just had the spark plugs replaced earlier this year. I put all new MSD coil packs on it probably @ 8 years ago. Would you think that the MSD's have gone bad already? I thought they were supposed to be top quality coils.....
    My truck has 240k miles on it and I'm thinking seriously about dropping a new engine in it. Any suggestions where to get a new or remanufactured 5.4 crate engine? Would a Ford dealership be the best option for an engine?
    I would appreciate any and all feedback. Thanks!

    Hey bud. Welcome to the forum. Tbh. All those coils stink. I ran threw them all in my 03'. They could go in 2 weeks. Crap shoot IMO But 8years seems like a good run. You've had some luck. But check the code it should b throwing by now to narrow down your search and just replace them as they go.
    I would try to find a place in your area that has remanufactured a long block and go from there. Or you could go through ford. Then u can have them service it anywhere. Anytime and it's on them. Good luck

    Hey thanks! I'm glad to be here! I really appreciate the information. I'll check the codes and see what I got going on. What brand of coils do you have on your truck now?
    Have you ever had to replace the IAC valve on your F-150?
