How do I fix rough idle
Hey Scotty, we have a 2013 Honda Pilot (120k miles) and everything runs great still, no issues while driving. When the car is in Drive and not driving, it feels and sounds like it has a sort of low rumble or rough idle. Dealer says they couldn’t find anything wrong, had new spark plugs and transmission fluid done recently and new timing belt too. Any ideas?
Clean or replace the MAP sensor also and get the fuel pressure tested in addition to what @yaser recommended. Please find a competent independent mechanic, not a dealer, for your services.
Run a diagnostic scan.
