kind of rhetorical question here.
I am going thru spark plugs like nobody's business lately, the engine is not running rich right now, although it was for the last 6 months. Since i fixed my FPR problem and changed my plugs its been at 100% for a few weeks, but now it started missing again so again i changed plugs...Runs great again.
Now i figure at this point could it be my cat? I have a Straight pipe sittin here that i am waiting to install for b20vtec.com dyno day in early Feb.

Anyone have an opinion here, the plugs arent really dark like its runnin rich, they just look fouled.

PS - The CAT has at LEAST 120k miles on it. 30k miles when i had the H23a1 motor, and 91k miles on my h22a1 since i rebuilt and swapped it in.
