Engine Performance problem
1999 Ford Escort 4 cyl Two Wheel Drive Automatic
i have 2 codes popping up P0304 (cylinder 4 misfire) and p0401 (EGR flow insufficient) I've replaced the EGR, and spark plug wires, and fixed a vacuum leak, but it still idles funny and chugs while i'm driving, the codes still come up. Do you know what could be causing this.
have the same problem?
