Toyota - Corolla - Transmissions :: 2011 - Tachometer Will Start Jumping At Constant Speed
Apr 5, 2011
I have a 2011 Corolla LE with the automatic transmission. When traveling at a constant highway speed (i.e. 60 mph), the tachometer will start jumping around. It will jump up than down by anywhere from 200 rpm to 1000 rpm. It only lasts a few seconds then returns to normal. The dealer is saying that is just the electronic controlled transmission selecting the correct gear. I have never heard of this in any other car.

My daughter's 2002 Saturn S-series coupe has a manual transmission. Lately it has been jumping out of 2nd gear, and occassionally 4th and reverse. What is the most likely cause?

I bought a 2011 Toyota Corolla brand new and the last several winters in the snow the traction has been terrible. Even at very slow speeds, it is difficult to get the car going and keep it straight on snowy roads. I have a 2007 Corolla also that was bought new and never had these similar issues with that car. The current tires on the 2011 car are Bridgestone Insignia SE with about 20k miles on them. But even with less miles, traction has always been an issue.

The problem began a year ago when the car would randomly lose power while hubby was driving it, and then regain power almost immediately and continue to move forward. Weird. Fast forward a year and the problem is happening more frequently. Couple that with the car taking a lonnnnng time to start up in the morning. One day, it ceases to start altogether. Had a mechanic friend of ours look at it and tell us we need a new fuel pump. Okay, no problem. We paid him for the pump and he installed it. Before I could dance a victory dance, though, as hubby turned the key....the car still won't start. Mechanic buddy takes another look at the car and said the ECM is cracked and needs replacement. Looked it up online and ECM is covered under safety recall. Had car towed to the dealership, waited 2 weeks on ECM replacement, dealer called us up to let us know that....the car still won't start, and looks like we need a new fuel pump.
Mechanic friend took another look at it and said it looks like a bad connection between the pump and made an adjustment to it. The car works! Sort of. Car starts acting funny again. We're driving along and the car is losing/gaining/losing/gaining power, tachometer goes up and down, we hear a funny clicking coming from the dash area every time the car loses power. Last night, the car just refused to start. This morning, it started. After several attempts. Made that fun "verr-verr-verr-verr-verr-verr" sound without the "-rooom" at the end. Since my knowledge of fuel pumps and their casings, ECMs, and the like are limited to this situation, I'd love to know what's REALLY going on with the car. I have a suspicion that it goes beyond the fuel pump situation, but mechanic friend thinks it is the casing or something like that.

This corolla is about 10-15 years old, i don't know how old. Again, its a manual transmission. It started today, when the car idles, the engine revs up a bit like a hum. I wasn't pressing the gas petal or anything and it just revs by it self. My dad says it was probably the engine was too cold and it is just warming itself. Then my dad said the car mechanic said its the gas sensor? He also said the sensor cost about 200 and with labor job, 280$. good deal?

On my way home late at night, my tachometer started jumping a little, and the engine was rough. Then after another minute the lights dimmed and the engine died. It wouldn't start again. The next morning, it started right up, and it seemed fine. Drove it to the mechanic, he took it for a drive on the freeway, then after he got off the freeway it died again and had to be towed. The error code on the computer is P0326- Knock Sensor. I had the same sensor activated a couple of years ago, and my awesome mechanic (we have since moved far away, so I don't have access to the same guy) gave the engine a tune-up and replace the spark plugs and everything was fine (well, for two years). The car has been idling rough, and the intake manifold may be warped. Could the intake manifold cause this? Distributor?

From stop. When I accelerate it takes a long time to get to drive. It feels like a lag time. What is wrong with my car?

I put a clutch and throw out bearing in it about 4 months ago. All the sudden driving went to shift from 3rd to 4th and it wouldn't go. If you turn the car off you can shift it into gears. BUT if you try to turn the car on in gear it just jumps forward. I have had guesses all over the board about what it COULD be. It seems like a very exact problem to me. BUT with that said I have never worked on a car, just drove one.

Mechanics say they don’t know what wrong… I had some transmission work done on my truck – mostly an leak and replacing the harness – and ever since then after it rains or if we have a heavy dew my truck does the following:
Driving from O to 49 miles an hour truck is fine, as soon as I hit 50 the truck starts surging and you can see the tachometer jumping from 2000 RPM to 2500 RPMs. I drive around 17 miles to work where my truck will sit for seven hours. On the way home the truck is fine. I find this to be more of a problem when the truck has sat for a day or two over the weekend without driving it. Sometimes the “check engine” light will come on, sometimes not.
I have taken it to two different places and neither one says they can find anything wrong with the truck. I have driven this truck for over 11 years and know it very well. There is something wrong, but what? 1993 Chevy Silverado 3500 Diesel....

In the last six months I've occasionally seen both the tach and the speedometer slowly peg when I start in the morning. My mechanic says to not worry about it but I do. The car is a 2005 Toyota ECHO with manual transmission.

Recently blew the belt that runs the water pump, etc while on a vacation. Had to leave the car at a small mechanic in Winthrop, WA. He replaced the Water pump which had gone bad and the belt that shredded. The car ran beautifully for a week. Now there is this constant rattling sound coming from the water pump area. I attached a video with the sound. The sound will quicken as you accelerate. At cold start up it is usually not present then starts a couple of minutes in.

I have a 2010 Toyota Matrix with the 1.8L engine that has a battery drain that is causing it to click and have a hard time starting after it sits. The clicking is constant, and basically sounds like a dead battery, which it is.
Battery was taken out and tested on a bench at Pep Boys, came back 100%.
Checked my voltage at night after driving it and it was at 12.5 V, checked again in the morning and it was down to 9.6 V. I know I have a drain somewhere, and have read I may need to keep a jumper across the negative terminal to ground until the moment I hook up the multimeter to it to check for a power draw? Is this year/model known to have certain issues with parasitic drain?

I have a 98 ford Explorer that has some serious trans problems. It all started a while back when I was pulling a small 10 foot trailer and when I go to where I was going the trans puked out what looked like all of its internal fluids. It was a hot day, and these problems seem to be exacerbated by the heat but who knows. Yes the check engine light is on. I also have the occasional O/D OFF light blinking at me. As of late the vehicle has started to act like it has a stall converter on it. I have to rev to nearly 3k RPM before it will engage.
I changed the fluid and filter about 2 months ago and the fluid is already grey and nasty. The vehicle has also started going FORWARD in ALL gears, Reverse, Neutral, etc. all are forward gears now. The trans occasionally overheats and pukes out a large amount of fluid but I cannot tell where it is coming from. At road speed (55 MPH) the engine surges when it is at a constant 2500 RPM. I know my outlook is grim but if I just need a new torque converter I would like to know before I go the the Salvage yard for a different transmission. BTW. The engine WAS replaced around 12,000 miles ago with a donor engine from a flipped vehicle.

I filled up my car three day ago and ever since then its been shaking when I brake and when I speed up and pretty much any time the car is moving. Why its doing this I just had it in the shop two weeks ago for a full check up. What the issue could be?

95 corolla, 260K trouble free miles.
Lately when the car is just "rolling" low speed about 5 mph, occasionally when I give it gas it kind of "slips"...the engine revs a bit but the car doesn't accelerate right away. It's like it's caught between 1st and 2nd. (It's an automatic).
Is this a sign the transmission is slipping? I do go up a very steep hill every day (my driveway) and I shift it into L to do that...I go up at about 3-4 mph or so for 40 yards or so. Maybe this is wearing it out?

When I start my '03 Corolla its idle speed is around 1200 and later after driving for a few miles it settles down to around 700. Other than that it starts well and runs smoothly. I tried to back off the idle adjustment screw and found out that the screw was barely touching the stop. In older models I used to be able to fix or repair the cold idle in engines with a carburetor, but am totally clueless regarding fuel injectors. This condition also happens when I start the car during the middle of Texas summer (100+ deg).
The car has 123,000 miles. I have not ever changed the plugs, but as i mentioned the engine starts and runs smoothly. As expected, the idle speed responds well whenever the air conditioner is turned on. The engine temperature comes to the mid gauge as always after driving a mile or so. No engine check lights come on. The car always passes the annual smog inspection.

Over the past month I've notice the idle speed increasing. Yesterday I had to turn the idle adjustment screw to lower the idle speed, as the high idle speed was making it difficult to drive in stop and go traffic. Especially if I took my foot off the gas while in gear, it would jerk rather than slowing down smoothly as it used to. I think the jerking was related to how the ECM stops the injectors completely when slowing down in gear, to improve mpg, then before the rpms gets too low, fire the injectors back up again. Anyway, lowering the idle speed with the adjustment screw fixed the jerking problem, for now.
But in 20 years, I've never had this occur before. The only time I've fiddled with the idle adjustment screw was during tune-ups, and then only had to adjust it 5-15 degrees. This time I had to turn it in 45 degrees. I expect there is unwanted air getting into the intake manifold somehow. And it will probably get worse. Here's some ideas -- in order of most likely to least likely -- I've had what could be causing it.
Throttle valve sticking in throttle body and needs a cleaning.
Throttle linkage needs a lube.
Canister purge valve is open during idle and allowing fumes from the canister into the intake manifold, when it shouldn't be.
Throttle position switch has failed.
Vacuum hose or device leaking.
IAC valve (part of throttle body in this car) is sticking.
ECM is bumping the idle speed through the vacuum controlled actuator (VSD). Unlikely, b/c the idle speed still increases when I turn the headlights on or I turn the steering wheel, both of which use this mechanism (I think).
Thermostat -- unlikely as it happens even when the coolant has reached 195 deg F (when the fan turns on).

I have a 2001 Toyota Corolla 5 speed manual that is having a hard time picking up speed, but the engine will rev as high as your willing to push down the pedal. The engine runs well its just not affecting the speed of the car very quickly. We replaced the MAF sensor recently and it made little to no difference.

Early 90's Toyota Corolla.
I've been hearing this sound the past couple weeks coming from the rear of the car. Not related to the rpm, only occurs if the car is moving slowly -- like when I'm driving in a parking lot, looking for a space. Occurs when turning, even slightly, but not when going dead-straight. It it intermittant, seems to occur more often on hot afternoons, never heard it all winter, or even now in the morning. Not that loud, but noticeable. Sounds a little bit like a vibration, sort of a buzzing sound, but more musical than a simple buzz.
The best way I can describe it is that it sounds almost exactly like that sound they make in kids cartoon shows on Saturday morning, when something bad happens, like one of the characters get hit on the head with a baseball bat ..." waah waah waah" .. sort of like a muted trumpet or muted trombone.
Rear wheel bearings? Brakes?

Clear water comes into car my Corolla 2011 on drivers side and both the passenger and drivers rear floor panels. I checked and not coming from the body. Think it's from A/C but it's a lot of water. Front passenger side is bone dry. Looks like it may be coming from the center console and spreading out. Could the A/C evaporator drain be plugged. If so where do I find the hose?
