skipping after car warms up; check engine
light indicates problem in 4th cylinder; injector switched from 4 to 3, problem code remains indicating problem in cylinder 4; PCM replaced (used PCM installed) and problem remains; current mechanic thinks the problem is with the "harness" but first he must replicate the problem; plans to take car in couple of days, let idle/test drive until skipping then examine harness to pinpoint the problem; reasonable? thoughts?
JA: Does the light stay on, or does it blink?
Customer: usually steady but sometimes blink (less than 10% blink)
JA: What is the model/year of your Ford?
Customer: 2003 Ford Focus Z5X
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: i won't be fixing it myself
JA: Anything else you think the mechanic should know?
Customer: my mechanic says this is not a problem with a major component so in his opinion the additional labor (3 hours) is worth the money
