2007 Honda Accord Q&A

problem just began, ans does not always happen, just when cold. No codes come up -
Answer 1
Bring to dealer or trusted , (with Honda knowledge) independent shop and leave overnight so they can hear it on 'cold' start-up. Possible 'VTC actuator' has failed.Make sure , if it's an independent shop , that they are aware it will only do it one time on first start , if it is the actuator.They can use Honda service bulletin #09-010 as a source of info for symptom diagnosis , but the bulletin itself only applies to '08-'12 accords and '07-12 CR-Vs. Hope this helps some. Strong suggestion , this job although not to physically difficult , can be trouble if it's not re-assembled correctly the first time!. -
