Spark Plugs

I have a 1994 Bonneville SSEi, I do believe that this is the series 1 engine?

I am having some rough idle problems and I think it is time for a spark plugs.

I am pushing about 8-9 lbs of boost right now with a cold air intake and the cold weather. I was wondering what type of plugs I should use and if I have to gap them at all???

I believe that you may want to try NGK TR55'*... I think you will want the gap at .055-.060...

There are a couple of others that can answer this for you.. We'll let them give a better answer

I'd go with the TR55'* at .060, seeing as you haven't swapped pulleys. I don't know what gap they come with at the store, but you can order them with certain gaps from ZZPerformance.com

replace the wires as well. I just changed my spark plugs not that long ago and after i did it the car ran like crap all of the sudden. Someone suggested I get new wires but I was stubborn about it and said they were good enough, eventually I caved in and got new wires and it'* back to normal
