Hello - I have a '99 Odyssey with 190K miles. CEL came on some time ago but van ran fine. Yesterday noticed oil was a little low and added about 1/3 quart of oil and drove van with no issues. Later in the day it started rough and CEL started flashing and then went solid and continues to run rough. Any thoughts? Thanks.

 

Hello - I just drove to Autozone and they downloaded the following codes from my 1999 Odyssey: P0300, P0301, P0303, P0304, P0306, P1399, P1457. Technician at store thought it may be the MAF sensor since he had similiar experience. Thoughts?
Thanks.

 

You have misfire on all 6 cylinders. When was the last time you did a tune up? New plugs? Filters? If you are going to buy plugs for it buy ONLY Nippo Denso or NGK!! These are OEM Japanese plugs that work the best in a Japanese engine. The P1457 code is for EVAP canister, either the solenoid is bad (most likely) or you have a leak in the hose. Its nothing major, does not affect the way the engine runs, but should be fixed.
