Hey Fellas,

The truck has been taking a dive lately with not only window regulators failing but the other day the truck started shaking something awful when accelerating in higher gears or going uphill and then the check engine light came on and stated the 2nd cylinder misfire. So besides getting the trans fluid flushed (which is was passed overdue tomorrow) I am having a mechanic buddy replace the ignition coil on cyl 2. My question is he said surprisingly performance coils are cheaper than oem ones (45 vs 60).... I dont necessarily have the money to change all of them right now so would it hurt my truck having one performance and the rest stock??? (Not to long ago I changed out spark plugs so thats not a concern)

Thanks!!

 

You wont notice a thing different, change the coils as they fail.

I've seen some go 10k miles beyond another failing. The only time I recommend changing more than one when a miss fire is happening is when you have to remove intake manifolds and/or plenums to get to one bank.

 

ok cool, so I wouldn't notice a change at all changing the 1 vs all 8... of course until another one went bad
