    My daily driver - 97 Furd F150 4.6L. 4x4. Air Raid cold air intake and K&N filter. OBD reprogrammed for harder shift and performance at 87 oct. (No chip) Engine replaced 2 years ago. 10K on new engine.

    I took off tonight from a stop sign fairly hard. About 3500 - 4000 RPM engine started popping and missing. No check engine light. I then noticed hesitation on accleration and slight miss. The miss was not regularly occurring. Still no check engine light.

    Would a REAL DIRTY K&N filter cause this? Any ideas on what would cause this???? :confused::confused::confused:
