I have a 2010 Honda Accord. Had some problems with the seal around my fuel cap cause the car to run poorly. Check engine light came on. Replaced the cap. The car seemed to be running fine. However the engine light stayed on. Took the car to the local part store to get the code read. Misfire on...

Hello! I have noticed my engine hesitating sometimes and cold starts are usually rough. Feels like the engine is about the stall. Pressing on the gas helps bring back regular rhythm. Once warm, the car seems to run okay and I don't notice much problem when on highway. But when in gear (D) and...

So I've recently been having a problem with my 03 Accord (V6 6-speed manual). 170k miles. One day I noticed that after I started my car it was popping a bit more than usual (it has an exhaust so it's not unusual for it to sound a bit louder on a cold start). Sure enough, the CEL started flashing...

I got new plugs and a belt put on yesterday and now my v6 accord is misfiring. Is it more likely to be the plugs or the belt that’s causing the problem. (or poor installation) on both. My ecu has also not thrown any codes which is surprising.

Please help. 2013 V6 Accord. Misfire code p0301. Moved coils around, didn’t notice difference but changed coil 1 anyway. Changed all plugs. After 30 miles or so, car will sputter when trying to accelerate and rough idle. Will usually reset if I turn off ignition for a few minutes. Mechanic said...

Hi everyone my name is Ryan. Last year i bought a 2004 Honda Accord EX 3.0 V6 6-Speed Coupe. I bought it with a blown motor, but i didn't care. I fell in love with the car and still love the car. I replaced the motor with a new/used one with approx 140,000kms (86,000miles). But recently I have...

Let's start from the beginning. I may overload you with details, but maybe something will be a clue so bear with me. I bought this car, it's been dealer maintained it's whole life, it now has 125k on it, I've had it for less than an oil change and it seems to be falling apart. I got a Cyl 3...

I have a 2005 Accord Hybrid with 130k miles, and over the past several month it has been experiencing misfires occasionally at idle with blinking CEL. This only happens when I first start the car, as soon as I step on it the misfires go away. It also doesn't seem to misfire once the engine is...

Hello there! First time poster and amateur car tinkerer here. Recently after reading through some helpful forums, I decided to replace all 6 of my spark plugs. Honda accord 2005 EX 3.0L V6. Everything went smoothly, tightened to the precise torque, sounded great when running. After driving the...

If you've found your way to this thread, your venerable 6th Gen Accord is probably experiencing the gremlin known as "heat soak" (a.k.a., "hot soak", misfiring after hot restarts, etc.), and/or its more insidious companion, the dreaded "random misfire" (P030x) code. First some backstory...

My 2010 Accord V6 finally got the dreaded misfire code, P0302, the one Honda was sued for and later settled with an extended warranty. I also had code 3400, which was as a result of low oil. My car has 86K miles on it. A little backstory, I'm very meticulous about changing my oil and...

I'm a new driver (10 months) and my 2005 Honda Accord hybrid is my first car. It started off with no issues whatsoever but in the past few months they've been coming in one after another! So first off, a couple months back my check engine light went on and I went to check the codes. The results...

I have a 2003 Honda Accord V6 4 door and have had multiple cylinder misfires at high rpm (usually above 4500) ALWAYS starting with cylinder number 1 then followed normally by cylinder number 2 then the rest. Before the brake warning light and the TCS light came on, we replaced all 6 ignition...

Hello all, I purchased a 2009 Honda Accord EX-L about 8 months ago and have had zero problems with it until a month ago. My check engine light came on and the car began driving very roughly so I took it to AutoZone to get it tested. It came back with random misfires, misfires on cylinders 1-3...

Hey guys. Recently bought a 98 Accord LX 2.3L 4 cylinder automatic for the girlfriend. 177k miles on the car and about 100k on the engine. The car seemed to be in decent shape, definitely an upgrade from her ol' 95 Geo Prizm squealing rust bucket. Started doing some general tune-up stuff...
