ignition coils bad?
I think my coil may be heading south but i have no check engine light. most people i talk to say it will trip a light...i have ruled out most everything alse and really think its a coil but have no check engine light and no codes at all. could it still be a coil? this is for a 03 SCrew 5.4 auto

What symptoms are you experiencing?

i replaced mine because i had bad acceleration without it throwing any codes, also replaced the spark plugs and it made a world of difference.. coils i got $100 for a set of 8 off ebay...

it is missing...usally when driving along at lower rpm it will start spuddering as you lay into the throtle as soon as it drops down a gear the spuddering goes away. also sometimes it feels like the engine is surging when climbing hills.

I have some of the same issues. im replacing plugs as soon as i have time in my final schedual. i would be intersted to find out if the coil packs help as well.

This is one way, most accurate way, you check/test for a bad coil, hope this helps future DIY'ers.
