Honda Accord Engine Sound
I have a Honda Accord EX V6, which has been running for 100,000 miles
now with minor problems. I have always followed the manufacturer's recommended service schedule and use Genuine Honda Parts for replacement. Off Late I have observed that the engine makes more sound than it normally used to make while climbing hills, or accelerating on a slightly inclined slope ( I feel like I am driving a V4 verses a V6, if you know what I mean). The pickup looks fine and the car does not show any other indications of fault, expect that I feel the engine is struggling more than it should for accelerating. Could there be anything that I can do to fix/diagonise it ? I have changed the following recently : 1. spark plugs 2. Engine Air Filter 3. Engine Oil ( Though I think I might have overfilled a couple of ounces, will this be an issue ?? ) 4. Canister shutoff valve - some leak near the canister, so the valve had to be changed. It has been atleast 500 miles now that I changed this part. 5. Added STP Injection Cleaner to the Fuel. 6. Started using Premium grade Fuel (93 octane) just to see if there would be a difference - did not find much ! Any suggestions are appreciated. Regards, -- John Edwards |
