I put Taylor shorties on top of iridium plugs (I didn't pay full price for these, it's nice to have friends) and got a little bit better gas mileage and the engine was smoother.

 

now im starting to wonder if my cat is going bad, it kind of spits and sputters while idling. Still not throwing a code yet.

 

did you just take one plug wire off at a time? or all at once?

If you took just one off at a time, it should have been simple to get them back to correct...

 

I did one plug at a time, and tried to run the wires as I did each plug. When doing wires should I replace the plug on each of the coil packs?

 

 

well I rechecked the firing order with the above diagram and everything is correct. I have found that it will idle at 500 rpm and that is when it runs the worst. most the time it will idle at 750-800rpm, but it will drop down till 500 and run worse.
