So this has me baffled. Last couple of weeks as soon as I floor mine 2005 V6 accord to obtain on the highway the inspect engine light would flash because that a short time. Vehicle ran fine and also noticed no issues. I had actually my friend hook up his computer system to scan the obd2 and also it proved no codes. Us think one of two people his password reader won"t job-related for this automobile which seems odd because it proved all the various other data of it or it"s some software program flaw through the check engine light? I had the battery replaced last month so maybe that resulted in a issue? five admins ns accidentally reported my article by mistake together I"m on my phone lol
Flashing engine irradiate is commonly a misfire may take a when to set a code. Occurred to me, turned out to it is in a negative injector. Examine your plugs & coils first.

A flashing CEL (Check Engine Light) is something significant to be pertained to about. A flashing CEL shows that her vehicle"s engine is misfiring, which can severely damage your catalytic converters. ... Engine misfire is a severe condition that requires prompt attention to protect against expensive repair or even a auto fire!

Like mentioned, inspect spark plugs if not already checked, and test ignition coils through a cheap spark tester.

I confirm the spark plugs and they look good. I filled the up v premium gas since regular has ethanol and also I"ve had that reason issues v a past car. Likewise put in party of injector cleaner and floored it, so much no flashing light. Just how would I inspect the coils if it"s only misfiring wide open accelerator ? If it to be happening every the time testing would it is in so lot easier
On my auto it would certainly misfire randomly, maybe twice a week but only if accelerating. Mechanic narrowed it under to cyl. #1. Coils & plugs to be OK, had a decarbon of engine done, vtec pressure switch changed. Rather of paying for maybe a lenghty diag. The mechanic believed a crank sensor or failing injector however most likely injector. Had actually injector replaced last Thurs., auto runs & accelerates much smoother.

Misfire. Ns recently had the same thing. Ns don"t recognize what scanner he used, but there is a code stored. Every time the CEL flashes, a code is stored until it"s clearing by a computer. Same thing occurred to me, 2005 V6. I floor it, CEL flashes. My spark plugs looked great, however they to be 172k miles old. Put new ones and also no an ext CELs once flooring.
the spark plugs look great but room older so probably i will try the simplest solution and replace lock all. If i only knew the cylinder that misfired it would be so lot easier however working on car is never straightforward lol. My last vehicle was a 98 Civic and the owner spent over a cool on a intermittent suspicion problem. I obtained it cheap and it took me month to figure it was a defective o2 sensor that would reason the engine to operation lean at random times leading to hesitation however it wasn"t negative enough to litter a code.
bobistheoilguy (rebates, sale, promo section) for a code. Order online with instore choose up, lock come pre gapped. When you traction the plug you will understand what cylinder.
My "07 had this exact same concern when that hit 120k. New spark plugs didn"t solve it. Brand-new injectors didn"t settle it. Valve adjustment solved it, and I"m sitting at 133k through no problems, no CEL.
OP,check your oil level. My automobile did this last week on highway, and also found that i was 1-1.5qts down on oil. Sent from mine SAMSUNG-SM-J320AZ utilizing Tapatalk
current car: 2015 Honda Accord LX I4 MT (check nine gen purpose of use thread because that weekly updates)* engine replaced at 339k mile (user error ~ above highway, x2)* transmission replaced at 501k miles
stiller pan This is absolutely a possibility. The accord the this generation v the V6 is well known for rear key seal leaks previous 130k, for me it"s about fifty percent a quart between oil changes.
^Have no done any type of valve mediate in 265k mile / 10.5 years.Rear main seal isn"t leaking either. Oil level does no drop in between change. I constantly use the same brand/weight of oil.What space you doing i am not?
stiller pan This is definitely a possibility. The accord of this generation through the V6 is notorious for rear key seal leaks past 130k, for me it"s about half a quart between oil changes.
t-rd might have something to perform with my model being a 6MT. I likewise did have a fairly severe overheating experience about a year ago, which most likely damaged the seal.
From mine experience, friend don"t need a valve adjustment unless you redline a ton previous 6000RPM. This is just how I to win up mine old 98 V6, that really needed a valve adjustment ~ that.And what the heck occurred that the engine overheated?! when it overheats, it"s never the exact same again.

t-rd Damaged reduced radiator hose on the drive back from Havisu come SD. I didn"t notice the temp gauge until the CEL came on, and there was a noticeable loss in power. Closeup of the door it off immediately and also had she towed. The oil leak verified up a couple of months later, it"s persisted since.See:
