07 F250 with 168k, needs new plugs & coils ?
How long do the stock plugs/coils last? One of our 03 F150s had a coil go bad at 113k... thats on stock plugs and coils otherwise though.
We already bought new plugs and coils for it but then 9 out of 10 guys say dont mess with them unless you need to change them... but we're getting p0300 codes, random misfires up above 4000 rpms sometimes and seems sluggish with any rpms over 3000.. could it be one coil or if its random its just the plugs and not the coils?
