  2. Check engine light and codes

    General Technical Chat
    Hi, My check engine light comes on and off on occasion. The last time I cleared the codes with my predator, I got these: B1681 - Unknown and P1000 OBD Systems Readiness Test Not Complete. I have the predator V.9R04. Anyone have any ideas what these are? Thank you.
  3. Air filter and check engine light

    General Technical Chat
    I removed the "lifetime filter" assy in my 05 2.0L ZX4 and put a K&N cone on the end of the MAF tube. Engine misses sometimes while cruising and check engine light came on after about 20 miles. Any advice?
