I was wondering if there was a way to check and see which one of your coil packs are bad. Anyone know of a way?

 

Unplug/replug them one by one and see if the idle changes.

Or check their resistance.

 

Well i cant really do the idle way because my cars already running ruff. Someone told me to replace the spark plugs and one of my resistors are prob. bad. I didnt really wanna buy all 6 because they are like 70 bucks a piece...

 

yes u can do it.

Every time you unplug a coil, the engine will run even more "ruff".

But, when you unplug the coil that is bad, the engine will run the same.

Think about it.

 

+1 = 2. Any other takers?

 

They're a little pricey
