Spark plug change interval?

Must have the older waste spark engine, eh? You can covert those, I think? New coils, plugs. Not sure if ECM needs flashing.

The dealership won't install the old nickel ones now, just the iridium. I hear conflicting info on if you need to adjust the gap if you keep stock coils. I just installed nickel. If my driving habits remain the same, I'll do them again in another 4.5 years, I suppose. I can see where it'd be a bother without that little gearwrench tool, but it made it pretty easy.

Wow that is weird. Supposedly the old stock coils couldn't fire dual coated plugs - the whole reason for the copper only 30k mile plug thing.

Obviously they've deemed you need to buy a new truck from them!

They'd probably like that, but it'll be another 5 years before I hit 100k if my driving habits don't change. I figure I'll be good for 5-10 years on this one, anyway. Maybe the 6th gen will tickle me more then the 5th gen has.

By then they'll be Bentley-Opel-Peugeot-Fiat-Volga Group. And oh, by the way, Chrysler.

Great job!

Did you go at them from the top or through the wheel well?
