Rough idle - only when wet weather
#11
Installed the new harness last night. It pulls good and hard off-idle, but still idles like crap some. Not as bad as before, but still noticeable. Still doesn't throw a CEL.

Checked the MAF sensor's harness. No cracks in the wiring casings. Going to clean the MAF tonight. Unsure of what else it could be. Also had the neg cable pulled over lunch to clear old ECU data on airflow... seems to pull a bit harder now, or that might just be where it should have been all along.

Ideas? Really don't want to take it to "a shop" and s**t money away (potentially) fixing this.
