my 98 mountain srx keeps fouling sparkplugs i put all new ones in went for a ride about 4-6 kms had to change 2 of the new ones. where do i start spark problem or running to rich any ideas?
 

your plug boots good,switch boots around see if the bad cyl. follows

is it the same cyl(cyl's) all the time??
 
not always same cyl but most often it's the one in the middle.I will change around the boots or replace them thanks alot
 
I replaced the boots today and went for a ride wow what a difference
