Well,
I have just changed over from my stock plugs to what I was told were 2 steps colder plugs, but ever since I did that the car would idle fine for awhile then would sputter abit then die.

If I changed back to the old plugs the car would run fine again.....

I have been playing around with the gap with no luck...

Has anyone ever seen this problem before?
Is there a certian gap need for colder plugs??


Thankx,

What plugs did you put in?

 

NGK BCP7EV


The guy I got this from runs a Nitrous setup in his Interga and works at our local parts shop, he looked it up and said that the plugs he gave me would be what I would need to run boost in my Max...


Thankx,

I am pretty sure thats your problem. Did a little research and that plug is for a Saab 9000 and its a Gold Paladium fine wire.

Here is the chart for Maxima's, if you have a 4th Gen I suggest copper NGK's which would be a BKR7ES.

 

And remember to narrow the gap by .004 for every 50 hp.
