hello

i put some ngk gp platinum spark plugs in my 1990 22re soon after the code 71 check engine light started coming on.. how come that would happen?

i went back to the ngk bpr5ey spark plugs and no more code 71 check engine light..

as anyone else have had the same problem?

 

Don't you already have a thread going about this same issue? Again, it is not your spark plugs, it is something else.
