Honda - Accord :: Hesitation During Acceleration When Cold On V6


Nov 23, 2014

I have a 2003 Honda Accord V6 that has some acceleration hesitation and general jerkiness, usually noticeable when the car has been sitting for a long period of time (overnight). The symptoms seem to dissipate after 5 - 10 minutes of driving.

When I begin accelerating, the car feels like it hesitates when shifting from 1st to 2nd gear. If I let off the gas a bit, then the car jerks a bit.

I'm sure it's not the transmission, because the dealer said the fluid and everything looks fine. Additionally, I have another Accord (2000) that does have a failing transmission and the symptoms on that one are very different from this 2003.

A couple of months ago, I was getting a CEL and had a friend of mine read the code with his OBD tool. It indicated that Bank 1 Sensor 1 was bad. I replaced it with a Denso. I think the problem got better at that point, but has "worsened" again over the past month or so.

Any clues what this might be? Things I can try? Ways to narrow down the issue?

Honda - Accord :: 2002 - Sluggish Acceleration / Hesitation - Clean The Fuel Injectors?

I have a Honda Accord EX 4 cyl. 2002. It has sluggish acceleration and hesitation problems. I put in new plugs and that improved it some. My mechanic says I should pay him to clean the fuel injectors. What will work best? What needs to be cleaned? Would new plug wires work? Gumout? Big differences in cost.

Honda - Accord :: 2009 - Jerking / Hesitation Chug While Accelerating

I have a 2009 honda accord, v6, auto, 46k. It has recently started to chug, most of the time, not always. I feel it in the gas pedal. Kind of a jerking, hesitation chug while accelerating. It only chugs between 20-40 mph, disappears after that. Someone suggested a spark plug problem, but I can't imagine it's that since it disappears after 40mph. Could it be a transmission problem?

Honda - Accord :: 1999 - Delay / Hesitation Between Pressing Gas And Engine Responding

1999 honda accord LX/AT, 156k, 4 cyl, automatic, original owner, been doing all the regular maintenance..

About a year back, got the EGR valve cleaned and then replaced due to some stalls.a month back engine stalled and gave up on highway 10 miles into the morning drive.had to put it in neutral, and push it to shoulder.. ignition would turn over, engine would try to start but wouldn't.shop replaced the IAC.. they didn't say if there were any codes..

All this while, in stop-and-go traffic, where i try to be efficient and keep pumping on thegas pedal and cruising as opposed to braking, i have been noticing adelay/hesitation between pressing on the gas, and the engine responding.sometimes i feel like a lurch, and fear that a stall is coming, but the rpm's pick up and thecar goes on.

If I am decisively hitting the gas or braking, the engine is behaving better!it is when i am pumping on the gas and releasing, that i observe this hesitation.. Also there is a delay in the car shifting into higher gear..

Honda - Accord :: 1999 LX - Whirring Sound On Acceleration

I have a 1999 Honda Accord (4 Cylinder, 180,000 miles). After a recent blizzard here in Wisconsin I am hearing a "whirring" sound coming from the front end of my car. I begin to hear it at about 10mph and it gets progressively louder and begins to sound like a jet at cruising altitude. The car overall sounds louder on the road. I checked for the possibility of snow/ice packed around the wheels or underneath the car but don't see any. A wheel bearing possibly?

Honda - Accord :: 1994 - Pings In Low Speed Acceleration

I test-drove a 1994 Honda Accord with 140K today. Looking for reliable car for relative, and this was one of the better options, on paper at least, in the price range.It drove like a used car, but I was concerned about one thing: A ping when accelerating from low speed. It didn't do it constantly, but only when going from a standstill or slowdown back up to speed. The seller said he'd been told it was an issue with the catalytic converter. I've been told that a higher octane fuel will sometimes quell a ping in an engine with no knock sensor.Is this something I should be worried about? Is the high-octane rumor true? The car was otherwise very nicely maintained.

Honda - Accord :: 1998 - Intermittently Hesitating Upon Acceleration

Mechanic could not find any codes on my 98 Honda Accord... The car was intermittently hesitating upon acceleration... There were no leaks or no burning odor. He recommended replacing the transmission and failed to adhere to code 3361.1... The car performed the same way after the transmission was replaced and he "could not duplicate" the problem and therefore could not fix it... He did state the clutch were burnt on the car. After failing a smog check I brought the car to a different mechanic who changed the oxygen sensor and the car has been running fine.

Honda - Accord :: 2005 - Steering Wheel Shakes Upon Acceleration

My 2005 Accord steering wheel shakes quite a bit when I start to accelerate. I had the tires rebalanced, and it's still happening. The dealership indicated that there was "play" in both axles, and they both needed to be replaced ..... There's 85,000 miles on the vehicle and it's in excellent condition, could this shaking be caused by something else ?

Honda - Accord :: 2003 Hesitating On Acceleration And Check Engine Light On

My 2003 Honda Accord with 101,000 miles started hesitating on acceleration, and a day later my check engine light came on. I went to the auto parts store to borrow one of their diagnostic computers. The code I received for the engine light was from my O2 sensor. What can cause the hesitation and the O2 sensor to read faulty? I have had several O2 sensors go out on other vehicles, but that hasn’t caused any other symptoms before. I would like it to be that simple, seeing as how easy they are to replace, but I don’t want to get my hopes up. Anyway, the car is parked now and I am taking the bus because I can’t afford to take it to a mechanic. I don’t want to waste any money by starting to replace things without having better direction.

Acceleration - Honda - Accord - Rpm :: 1987 - Gulp Noise While Engine Warming Up

This morning I went to start my car and while the engine was warming up (it's carbureted, not fuel injected) I heard a strange sound that I can only describe as sort of a "gulp" or something. As I was driving to the doctor, at one point I was going up a slight hill so I went to accelerate and the RPMs reved up but I didn't go any faster than I was going, which was about 30-35mph. What's going on here? 1987 Honda Accord LX....

Acceleration - Honda - Gasoline - Accord - Fuel-economy :: 1990 - Shakes And Bad Gas Mileage

I own a '90 Honda Accord and it constantly shakes, has poor acceleration and seems to use too much gas. I thought it was the catalytic converter and I installed a high flow cat. The fuel pump went out so I had that replaced. It shakes less since replacing the cat but I still see the gas gauge go down too low when I press on the gas and the car will stall and stop as I get to "E" when normally I was able to drive many miles past "E". Any guesses? I'm wondering if I need to replace the fuel pressure regulator.

Honda - Accord :: SRS Airbag Light On Only On Cold Days

Since December, I have had the SRS airbag light indicator come on in my 2006 Honda Accord (EX-L, 2.4 L, Automatic), but only in the morning, and only when the outside temperature has been below freezing the night before. After a few minutes when the car warms up, if I turn the car off and then back on the SRS light is gone. The rest of the day, no problem. Figuring that it was not the safest thing to drive with, I had it checked out by a repair shop that I feel comfortable with. They checked the code and said that it showed up as a faulty SRS computer, and the computer would need to be replaced. It seems crazy to me that a 2006 Accord with under 52,000 would need a new SRS unit, so I started looking online to see if I could find any info.

I saw about the SRS units in previous Accords, but it seems like they have those issues ironed out in the 2005 and 2006. I did however, see that some people have said that low voltage also could trigger the same defective code in the SRS unit, which got me thinking. The original Honda battery died and was replaced at the end of November with an AC Delco ACD 51R60 (460 CCA). My original theory was that the AC Delco battery was not cranking enough when it is cold compared to the old Honda battery, and it is triggering the SRS airbag light. I ended up having the shop switch out the new battery to an AC Delco 51R6YR (500 CCA). Unfortunately, however, it did not fix the problem. I can't get past the fact that if it was a defective SRS unit, why would it only cause a problem for the first few minutes when it is cold, and then consistently be fine after that?

Honda - Accord :: 2004 - Engine Noise When Cold

2004 Honda Accord with 120k miles sounds like an old sewing machine when cold for a few minutes (less than 5). The exact sound is on a video on youtube: [URL..... Dealer said they can't find it. Car has been maintained well and all services have been done. I've heard a lot of guesses (all expensive) but no solutions. Dealer finally got tired of me asking about it and said to just ignore it (turn up the volume on the radio).
