My 2006 Tundra with 45000 miles on it has an engine vibration in neutral between 1400 and 1750 RPMs. It does not feel or sound like a miss fire rather a definite vibration. I have heard this is common with Toyota 4.7 litre engines. What might be some things that could cause it? It has always done it and after 8 years hasn't resulted in any engine failures.....yet.
View 5 RepliesI have a 3.3L 2007 Sonata. Within the past month, after first turning it on in the morning, the RPMs shoot up to about 1400 and slowly come down to normal after about 5 minutes. It does this in park and neutral, when I put it into drive it goes down to normal. If I drive it for a mile and put it back into park and neutral, it idles at a normal RPM. If I turn the car off for ten minutes and start it up again, it idles normal at about ~850 RPMs.
After doing a bit of google research, a lot of sites say that this is a normal thing for a cold engine to do. However, the RPMs have never gone that high previously. The check engine light hasn't come on.
I have a 2008 Mazda3. The car has a replaced engine with 24,000 miles on it. The engine was put in before I bought the car.The car and engine run like a top; except at certain RPMs and when in gear. When I have the car in any gear (auto), the engine makes a rougher noise at RPMs 1400-1700. As I apply more gas, the RPMs seem to get stuck at 1700, then it will break through and run smooth 2000+ RPMs. The engine sounds perfect at all RPMs except 1400-1700 when in gear. When I have it in park and rev the engine, the engine sounds perfect at all RPMs.

View 1 RepliesWhen I bought my 2007 tundra used a year ago, it has always had a vibration that affected the whole car (not steering-wheel specific), and was worst at 60-65mph, but a hint was there even at lower speeds. It was annoying, but bearable, for example if you look at the passenger seat at these speeds, you can see it wiggle back and forth about 1/2". It seemed highway speeds were where it hit a resonant frequency.
In the past month, things have gotten much worse and when the truck has been sitting for a few days, if I quickly leave the house and hop on the freeway (only about 1/2 mile away, I get a vicious vibration mostly in the steering wheel and less so in the rest of the cab. The wheel wiggles about an inch and a half back and forth at highway speeds and letting off the gas, braking, accelerating doesn't make much of difference, just speeds up or slows down the vibration frequency.
The wild thing is that it gets much better after about 2-3 miles. No longer really shaking, just a mild vibration like it has always had. If the truck is warm and I hop back on the freeway a few hours later, no vibration, just when leaving the house in the morning.
2006 Toyota tundra starting problem only intermittently, id say about half the time recently it does this. Ill go to crank my truck, turn the key over and it makes a loud CLICK/thud under the hood. Lights go dim, clock shuts off etc. Turn the key off and back on, CLICK. I have to repeat this 3-4 times before starting sometimes. And once or twice the starter would turn over for 3-4 seconds before finally firing up. Ive check the battery and alternator at the local auto zone and a local dealership, both checked out fine. The starter is under the intake manifold. I have checked grounds/connections etc but dont see problem.
View 3 Replies2008 Tundra 5.7 only 55K miles – What is causing an intermittent misfire at startup? It’s been running great, then 2 weeks ago when I started it up I could feel a misfire. By the time I backed out of the driveway the check engine light came on. This is what I have learned so far:
•It only happens when you start the engine and the engine is NOT at operating temperature.
•The engine code always reports misfire on Cylinder #2 I put in a new plug and swapped coils but it still reports the misfire on cylinder #2.
•Once it starts to misfire it will continue to misfire until the engine is at operating temperature and you restart the engine. NOTE: You MUST restart the engine for the misfire to go away. It will be running rough, turn engine off/on once it is at operating temperature and it's as smooth as can be, no more misfire.
•One time I started the truck, I felt the misfire and drove it to a parts store to read the code. Engine was fully warm by the time I reached the parts store. I did not power off the engine, plugged in the tester and read the code which was a misfire on cylinder 2. I cleared the code and within 2-3 seconds it logged the misfire on cylinder #2 again. Cleared the code several times and it kept reporting misfire on cylinder 2. You could also feel the misfire happening. Turned engine off, started it right back up, like before no misfire, cleared the code and it no longer reported a misfire.
•This just started intermittently happening. This morning it happened again, I drove it for about 5 min, engine was about 75% it’s normal operating temperature, powered it off/on, still had the misfire. Once engine temp reached normal temp (about 9 min), I turned off engine, started it back and like before problem was gone.
What is causing this to happen?
The vehicle: 2007 Tundra, 5.7, 4WD, SR5, 71K miles
The issue: The Check Engine, VSC and 4LO indicators came on abruptly within 5 minutes of the first start-up of the day and after driving ~ 1/2 mile on paved road. Weather conditions: high humidity and unseasonable high ambient temperature.
What has been done: Immediately returned home. My local "guy" stopped by with his code checker. Codes that came up: C10201 and P2440 (Wheel sensor and secondary air pump, I am unsure which is which). Codes were cleared, indicators went off. Within 0.2 mile of driving "around the block" the same indicators and codes came on. My local guy recommended a trip to the dealer for repair as he would have to get sensors/parts from Toyota and be replacing sensors until the problem was repaired (I respect him for that).
The question: what is the guesstimated cost for dealer repair? The truck can be operated in a "failure" mode and can get to the local dealer under it's own (reduced) power.
I have a 2003 Toyota Tundra V8 - 2 wheel drive. I have 121,000 miles runs great, uses no oil at all. However, on cold mornings when I start it, there is knocking in the engine for two or three minutes. Is it serious? Is it a weak oil pump? Rod bushings? I had an '01 Tundra with 165,000 miles that never knocked.
View 9 RepliesI drive a 2008 Elantra automatic,and have a constant engine shudder/vibration whenever the rpms are between 1000 and1500. The engine shudder stops as soon as I accelerate above 1500 rpms,or take my foot off the gas completely.
The dealer recommended cleaning of the fuel injector system,not sure if thats the course to take.I do know my model has had fuel pump issues,but the dealer has told me all recalls on the car have been processed.
I have a Toyota Tundra that shudders under acceleration. Its an A/T two wheel drive. Engine rpm remains constant, vehicle shudders.
View 2 RepliesI have a 2010 Dodge RAM Hemi Laredo pickup. Love it. Currently 34k miles. Have kept up with all maintenance. Since about 3k miles, I have intermittently heard a "grinding" noise at about 1400-1500 rpm. Usually while accelerating going up hill/inclines. Assumed it had to do with automatic gear shifting. Have reported this to dealer maintenance folks at each visit. They have reportedly not been able to identify the source, as they claim they do not hear it, despites numerous test drives. Everyone who drives with me has heard it!. I am concerned, as at 36k my full coverage for the transmission warranty expires. Incidentally, at 33,100 miles 2 broken studs were extracted from right exhaust manifold. A new exhaust manifold gasket and 2 new studs were replaced for a different niose. Are these related, or any clue about the "grinding" that I still frequently hear at 1400-1500 rpms?
View 9 RepliesAt the beginning December I put my brand new winter tires (general altimax arctics) on the factory steelies and put them on the car gearing up for the snow. Not to long after the install I notice that I was getting a very strong engine vibration starting at 3,000 rpms and it stopped around 3,100 rpms no matter what gear I was in. At first I though it maybe just the cold affecting the engine. Well...
Last week I put my summer rims and tires back on for the 1,600 mile trip to MO and back, and like magic, no more heavy vibrations. Smooth acceleration throughout the normal driving rpm range. I just changed the oil and tranny fluids Tuesday after we got back and with the warmer weather the car is running smooth as silk. Still an awesome car with awesome mileage and couldn't be happier.
What could cause this? I have 100k and I only notice this if in park or neutral at 1500rpms. It goes away before and after and it seems to drive very smoothly. I had a bad alternator and I just replaced it but the "new" one is making a high pitching ringing so I'm having the shop change that out for a new oem. Any chance it's the alternator or could this be something else. I have sea foamed the throttle body recently and cleaned the maf recently and changed the air filter. I didn't do plugs but they are do at 120k
View 7 RepliesThe car is an '05 elantra, 97,000 miles, auto., car is new to me. First time on the freeway today, 30 miles @75-85 mph, at the end of the off ramp I could feel it surging, shift to neutral rpm's went to 1500, hoss the gas and back to normal. On the return trip off ramp, went to neutral, jab the gas, everything OK. I'm going to clean the throttle blade, check things, etc.
View 3 Replies2002 Elantra engine is revving up to 3000 rpms when in neutral or park. I changed the Throttle Position sensor and it went right back to revving up. Code read P0121. What might be causing this? Seems like I get one thing fixed and then another code shows up..
View 2 Replies2008 Expedition 6 speed auto .... I recently had the clutch replaced in my manual transmission car. Whenever I am about to stop in traffic, if I put the gear to neutral I can see the engine's rpm hovering around 1080's rpms, and it only drops to the "idle range" of 700 - 800 rpm if I stop the car completely. I did a test going downhill in neutral and I can see the engine rpms going up a little bit if I let the brakes go. I plugged my obd scanner and used OBD doctor on my phone to keep track of the rpm graph. Here is a pic.. You can see the rpms going 1000's steady and then dropping abruptly when I completely stop the vehicle. So, is this normal?
View 18 Replies06 F550 w/5r110w. Truck and trans runs great then trans acts like it was shifted into neutral, rpm's flare up and if you don't get your foot out of it the trans will re engage aggressively. Changed the speed sensor on the rear axle, there are no codes, had a trans shop change the filters and fluids then change out all of the solenoids. They tell me its not a trans problem.
View 3 RepliesI am having issues with my 2003 F150 4.6L truck. It just happened today when driving home. It started fine and then when I increased the speed and the rpms went up to about 2000rpms, the engine seemed to slip into neutral. I stepped on the gas but the truck would not accelerate, it was just coasting. I pulled over to the side of the road and came to a stop, but didn't shut off the engine.
After a few seconds, I proceeded to give it some gas, and it engaged in gear and accelerated...until I got to about 25mph & rpms increased to about 2000 again. It did the same exact thing....seemed to shift back to neutral so that I could not accelerate. I had to keep pulling over to come to a stop, and then slowly proceed again. I wasn't too far from home & I made it. What this issue could be?
I have a 07 Sonata 2l crtd, Its been running fine for about 6 years, But for the last couple of months, when setting off gently, as it reaches approx 1400rpm, I get a blip/hiccup/flat spot/miss. It ONLY happens at 1400rpm, and irrespective of what speed I am doing.
For example, as above, (setting off) but also, if cruising gently at approx 50mph ( which equals approx 1400rpm) then it does it again. It only does it at 1400rpm.
Also (maybe related) the orange engine warning light has now come on ( twice in past 2 weeks ) it stays on for a day or so,,,then goes out. its not flashing.
My 2009 Hyundai Accent 3-door GS (I believe) recently starting idling around 1,000-1,400 RPM. The car (since I bought it new) has always read "0" on the tachometer when I was stationary. Nothing has happened to suggest this problem would appear.
The engine isn't very loud to begin with, so I'm not absolutely positive that it isn't just an error with the tachometer, but I THINK that the car is actually idling higher than usual. The tachometer works fine otherwise, when I am driving.
What could be causing this and the corresponding fix? The car is under warranty, so I want to attack this issue as soon as possible.
