Honda - Accord :: Tac Momentarily Jumps Various Hundreds Of RPMs When Accelerating And Shifting
Apr 11, 2012
I have a 2012 Honda Accord EX with a manual trans. It's a fly-by-wire system. When accelerating and shifting, the tac momentarily jumps various hundreds of RPMs when the clutch is in. That used to mean you weren't coming off the gas when the clutch was in. I've been driving manual trans cars for 45 years. I know how to shift. But, it was a new car, so maybe... I paid close attention and was not screwing up the shifts. Apparently the computer doesn't realize the clutch is in and the gas pedal has been released. Is this normal for these cars? Is it a problem? (other than wasting a half thimble full of gas and over-reving the engine?)

I have a 2005 Hyndai Accent GT automatic (83,000 km) and I am having a problem with the gear shifting. It's happening more and more.
As I am driving I am pretty sure that it's changing to a higher gear but when I slow down it seems like its not shifting down at all. Coming off the Highway I have to slow down and when I speed back up it seems like its still in the high gear. The RPM's instantly jumps up.
The only way it fixes it self is when I pull over and shut off the car and then start it up again and I am fine. A friend at work said that I may have to have my transmission fluid checked and filled up.

It has been so effective to add diesel injector cleaner to my 2004 Honda (all of 62,000 miles on it), that it is scaring me. Am I damaging anything? I add about an ounce/gallon every once in a while. Mileage drops back in between.

I just changed the engine in my 96 Honda civic, 1.6 base model. The change over went well and had no problems. When I have the car idle and it gets up to temp, the RPM's go from 2000 down to 500 then jumps to 2000 then down 500 again. When I put it into gear, drive or reverse, it stops jumping. What did I do wrong?

I have a 2007 Honda Accord EX (4-cylinder) manual. When upshifting, after pressing the clutch and my foot is OFF the gas, the engine stays at 2000 rpm for a few seconds before falling back; often it even INCREASES speed with my foot OFF the gas. This happens only when upshifting/accelerating and even when the car is warmed up. Is it a bad sensor, computer or throttle control?

I recently purchased 4 brand new michelin tires. They are approximately 3 months old now. Beginning a couple weeks ago, my car started shaking profusely at 60mph when accelerating. When I let off the gas, it would stop. I went and got a tire balance thinking that was the problem... but it's still happening, and now it starts at about 55mph. I have no clicking sounds when turning the wheel, and my car runs great besides this! What this could be?

I drive a 2003 Honda Accord and it shakes violently whenever I'm accelerating between 55 and 65 mph. If you put a shaker on the passenger seat, you'd have a martini. Approaching 55, it's fine, and then it shakes as I go up to 65 and then smooths out when I pass 65. If I am cruising, but not accelerating in between 55 and 65, it stops shaking, but once I hit the gas, it shakes.
The same phenomenon occurs in both third and fourth gears, so it doesn't appear to be related to what part of the power band the car is in. This model Accord had a recall on the engine mounts, which I had replaced at no small cost already.

My 1990 Honda Accord just recently started sputtering and shaking a bit when I reach 1500 rpms, if I'm under that she's fine and if I accelerate passed that she is fine.

I have a 2006 Honda Accord that just today started acting weird. I was driving 70mph on the highway and noticed the car was "tugging" a bit. I looked down and the RPMs kept revving up to 5-6k and accelerating while the cruise control was set at 70.

My 93 previa recently went in for brakes, shocks, and tune up. 320,000 miles original owner. Afterwards it ran rough. The o2 sensor needed replacing. When I got it back it ran rough. Mechanic assured me it just needed a little time. It has the following issues:Left front would shudder like an out of balance tire between 50-70. Replaced tire. Now it hesitates and stutters at 70. Feels like its choking out. Won't climb hills without shifting a lot. No pick up. Gets 12 miles to the gallon instead of 20. First three minutes of driving are okay, after that it rides terrible. I have him looking at it now. He swears it is just because it's old.

I have a 98 Honda Accord EX Coupe V6 with 175,000 miles. In the last 500 miles, I recently starting hearing a gurgling noise when I accelerate. It is rather faint and it goes away when I either let off the gas or my speed is constant. Also, I haven't noticed any appreciable loss of power or a decrease in gas mileage, but I am curious as to what the noise could be and if I need to have it serviced.

My 2001 Honda Accord LX automatic transmission with 103,000 miles has been shifting roughly for about a year. The car is in excellent shape otherwise. I've changed the oil & filter regularly @ 3,000 miles, just had the rotors turned. Last year, based on what the manuel says to do, I had the transmission fluid drained and replaced. It seemed better for about 6 months. The rough shifting seems to happen most when going from 2nd to 1st and vice versa. Last week when I accelerated to take off @ a traffic light it made a huge clunking sound & it was like I went over a speed bump as I took off. That sent me to a transmission shop!
Through a test drive & putting on the scanner, shop #1 says it has a major transmission malfunction & said need to take apart, rebuild & put back together. Shop #2 does the same testing & says basically the same thing & all they can tell me to take it apart & put it back together, with the unknown being what is wrong & what will be the total cost! Shop #3, same testing, but they went a step further and dropped the transmission pan & found the forward clutches in there. They recommended rebuilding transmission, replacing forward clutches which includes torque converter, pump, gasket seals, etc.
My specific questions are:
1) What is the function of the forward clutches?
2) Does the diagnosis & remedy sound correct

I've had my 2000 Honda Accord V6 for about 3 years now and have had an idling issue pretty much since I purchased it. After driving for at least 50+ miles, and if its hot out it can easily have this issue as well, and leaving the car be for around 15 to 30 minutes, on start up the car drops RPMs immediately and dies. Multiple tries and it will do the exact same thing. Recently I found out a trick to make it work correctly which is revving the engine to 2000RPM for about 3-4 minutes, slowly dropping it down to 1500 RMP for around the same 3-4 minutes and finally down to 1000 RPM for an additional 3-4 minutes and letting off the gas. Usually after doing this the engine idles fine, car drives great. However, it must be noted that on Summer days with temperatures in the 85+ range, if I'm climbing (going up a hill for a long distance) the car might bog down on me, will not go above 50MPH and I have to pull off the side of the road for 45+ minutes before the car will run correctly again. This has happened about 3 or 4 times in the 3 years I've owned the car.
I would rather not have to rev the engine in hopes this fixes the issue each time so I'm wondering what could be the cause in the first place? I've replaced so many things including spark plugs, ignition coils, battery, idle air control valve, gasket, fuel pump, fuel pump relay and on. I gas the car up with Chevron gasoline, I've dumped in I don't know how many different fuel injector cleaners and have also tried Heet as well as Sea Foam cleaner. I've also had the car checked for vacuum leaks.
I've asked multiple mechanics if this could possibly be a vapor lock issue, but they all turn that idea down. They tell me that since the car is fuel injected this can't be the issue..but, I don't know, could it be the issue?

My wife's 2006 Honda Accord makes a strange noise when accelerating. The best I can describe it is that it sounds like Woooo. It does not make this sound when driven at a constant speed. The car is in great shape and does not appear to have any mechanical or electrical problems.

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?

I have a 2004 Honda Accord EX 4 cyl. with 156k miles.
A couple days ago, the CEL came on. It drove fine, but if I accelerated it wouldn't shift smoothly. It felt like it was hitting the rev limiter.
I took it to get scanned, but the reader didn't work. On my way to another shop, the light went off.
Today, the light came back on with the same symptoms. No shops were open, so I disconnected the battery hoping to reset things, and it worked! No other issues on the way to work. Smooth shifts, smooth idle, simply normal.
Obviously there's an issue. Getting it scanned is a pain; AutoZone and the like cant scan in CA any more. What is the culprit? I'm guessing O2 sensor.

Had my original clutch replaced by mechanic. Had 200K on it. Car clutch petal vibrates badly when bringing clutch pedal out after shifting. Mechanic states it has to do with motor mounts that were affected when changing clutch or the clutch takes time to seal and stop vibrating in the next 500 miles. I have warranty for 12 months and 12,000 miles. Which I had no problem of vibration before having clutch replaced? What is the problem and how to proceed.

After a round of extensive maintenance this month, I thought my '02 was once again a road-ready betty. Just my luck! On the drive home from the shop Friday afternoon, I noticed a hard shift when upshifting from 2nd to 3rd. I've done some test driving over the last couple of days, and here's what I've noticed:
1) If I apply too much gas, I intermittently get a little bump—very subtle—when it kicks into first gear from a running stop. The car seems to engage fine at start.2) If I apply too much gas approaching 30MPH in 2nd gear, where I think it would normally shift into 3rd, the transmission upshifts late and hard. The more gas I apply, the harder the shift.3) Once, when gunning it at highway speeds, I got a little bump shifting into a cruising gear at around 70MPH.
I'm able to completely eliminate this problem if I am prudent with the accelerator. If I back off the gas before the tachometer hits 3000RPMs and wait a few seconds before accelerating again, the transmission shifts smoothly. I have not noticed any issues with coasting or downshifting.
I've had this car for a decade and 146K miles and it's driven like a dream every day until this symptom presented on Friday. I don't remember the last time the transmission fluid was changed, but I've never missed a scheduled service and I always use Honda dealer shops. I checked the fluid yesterday, and I think the colour (winey red) and odor (sweet) were both good. The car had been driven recently, and the level on the dipstick was higher than the second dot.

I have a 1983 Honda Accord (manual with nearly 200,000 miles) when rolling to a stop or at a stop rpms drop below 1000 and it stalls out. I can start it back up without hesitation.No hesitation at initial startup or after sitting short or long time, it idles while in park rpms about 1000.When I feel the engine about to stall while rolling to a stop or at stop, if I put my left foot on the brake pedal, slightly step on the gas pedal with my right foot it prevents the engine from stalling. At stop if I put in park, rpms raise and don’t need to give it gas.
I'm unable [& unqualified] to work on my car. Given I drive only about 1,000 mi year; my alternate form of transportation is a bus or kindness of friends, I’m on a limited income, cannot afford to buy/ spend more than 2,000 -- my question if 2-foId, 1. is it possible that something it is nothing major and worth repairing/replacing (ex. air control/idle air bypass valve, a dirty throttle body or even carburetor)?2. Or, as discussed with one mechanic, since the car is 33 years old, during or soon after repair other problems (dried out vacuum hoses or major) will follow. Plus, parts can be difficult if not impossible to replace as a I spoke to mechanic pointed out.Given the car’s age is it worth repairing?

I have an 04 Accord EXV6 with 237K miles. I have recently replaced shock absorber assemblies and all 6 motor mounts / transmission mounts, which resolved most of the loud "clunking" noises. However, I now have more of a "rattle" sound which I hear when one of three things happens...First, when the engine is started (typically when the engine is cold). Secondly, when shifting between park, reverse, and drive (also, more common when engine is cold). Lastly, when driving over rough roads or potholes at slow speed. The sound is the same in each of the 3 conditions, and appears to be coming from the right side. It doesn't seem to me that any bushings, control arms. etc. would be the cause since the same sound is heard during startup or gear shifting while the car is sitting still.

My car is a 99 honda accord v6 EX (coupe)It started overheating about 2-3months ago. I was driving along and the needle on the gauge was completely on hot. I was able to make it home. Ive basically been driving it this whole time with the defrost on 80 and on full blast. Which keeps it around the halfway mark between hot and cold. I had a friend change my thermostat .. didn't fix it. Still overheats. But after he did that it seems to get hotter faster now. When I am at a stoplight it gets as hot as the gauge will let it go, then when I start driving again it cools down a little.
Now, after he changed the thermostat the car has been driving really rough. When I slow down to stop, it'll jerk a couple lightly then stop. When I accelerate from a stopped position it'll jerk a little then go. And when it shifts gears(its an automatic) it jerks very noticeably. So now im freaking out worrying my transmission is going too. So I guess what I am wanting to know is ... wtf is wrong with it??? Water pump? Ive been told if I change the water pump I need to have them change the timing belt too .. yes?
