Check Engine light/ CAT Code/ VSA

2010 Honda Accord 2 Door Coup V6 187064 miles
I recently bought this vehicle with the check engine light on and I asked him about it he said “nothing to worry about”, but I got it looked at and it was a CAT code; I was thinking about getting spark plugs replaced or looking into the O2 sensor before looking into the Catalytic Converter, but recently the check engine light started blinking and I thought to myself that it could be going into limp mode. But there is a VSA light indicator on my dashboard as well idk if it’s just a malfunction or I need to get an alignment but I need to know. As well I feel like my transmission is slipping.

Mine feels like at times isn't getting enough gas, high idle but sometimes @ stops wants to dye. When got diagostic check,, Mach said could be spark plugs, ignition coils or o2 sensor. Which one is it. Can't the machine be more specific. Thank you

A mechanic of mine’s said spark plugs and ignition coils so we could possibly have the same issue.

Just put in a new battery...new alternator...all new spark plugs and coil pack...new purge sensor... I do not think it could be the starter because they is no clicking...and we ants to turn over...maybe fuel pump? Or O2 sensor? I had it scanned and it came back as emissions or HCAT...

2009 Accord 3.5L EX-L fix

2009 Honda Accord EX-L V-6 Sedan 3.5L 5A
I have had my honda accord 2009 v6 serviced for constant spark plug fouling and oil consumption. After a total of 10 visits, and over 40 days without my car over the course of 3 years, i had received a total of 3 spark plug sets, two oil consumption tests, lost two catalytic converters, and o2 sensors. Even with this constant spark plug replacement, it did not alleviate any issues. I kept breaking down on the side of the road with a rumbling, misfiring engine. After numerous trips to honda, they refused to acknowledge the problem. After speaking to a district rep and being referred to paragon… Read complete

2010 Accord EX-L problems

2010 Honda Accord EX-L V-6 Sedan 3.5L 5A
While attempting to pass a semi-truck on a two lane highway, my 2010 honda accord v6 lost power a few minutes after acceleration. The truck driver probably felt that i was being rude and slamming on my breaks, but i was trying to move to the shoulder of the road because my car was losing power. The car was towed to an independent shop that specializes in honda makes/models. Upon review of the vehicle, the shop found oil in all three catalytic converters. My 2010 honda accord is part of the class action lawsuit for misfire and oil consumption (leakage). I called honda america and notified the c… Read complete
