Posted on Apr 02, 2015. Note: The list of problems below is organized by vehicle generation. Basically, anything unusual shaking coming from the engine is worth to take a look. Anyone got a comment to help. After reading your thread, I figured, what the heck, I'll replace the mount and see what happens. But the fact that this one new mount has completely cured the vibration issue, truly amazes me! I'm guessing this is the cause, but would like your input as well. This is an honest question as I know deposits in the throttle body, especially around the plates, can cause idle issues on older cars.
Because if the throttle blade has carbon deposits on it, there isn't room for air to go by; the blade does not go fully closed. Do you have any idea how much this would cost? The only solution for that is to install the new ones right after this. Advantage of this is better fuel economy and quicker shifts - more suited to these smaller displacement engines. They are either out of balance, and would need to be rebalanced, or it is possible although remotely that the tire s may be compromised after hitting a pothole , the belts in the tire may be corrupted. I just recently had to have my transmission on my 2001 corolla changed due to failing bearing. I dunno, the car seems to be running fine, I changed the plugs, oil, pcv valve, and I think it may have gotten better, but it does still slightly vibrate. I drove my wife crazy last weekend.
At least that's how I look at it. I specifically used to tell everybody that right when I go over the edge of the hill, the vibration goes away. I really thought it has a vacuum leak but I could be wrong. I am very surprised your Toyota dealer didn't catch this! Assuming that it is an idle problem, and not a noise thing making the idle seem low, then cleaning the throttle body may help. I think i just got to the bottom of the issue.
Nothing else has been changed. I won't be going back to that dealership any time soon. Probably just a tire balance problem. It could also be a misfire, but the way you have described the problem, I doubt it. I hoped that this would be the last of my problems with this car.
Initially I was promised a 25% discount but when I arrived to pick up the part the discount had not been applied. A 10 minute operation with a rag and some carb cleaner not sprayed into bores, mind you changed that quickly back to normal. I have a vibration that starts at around 60mph. It started but I could not go forward or reverse it. The sign of awareness for this case is the cracks and holes on the vacuum hoses. I wasnt sure about the vacuum lines thanx for clearing that up for me. Some of the codes are described as under: S.
Lastly, the fuel intake system can also create shaking, even when your car is not moving anymore. I noticed that when the car was still under warranty. Hey whats up guys, i've been having a problem with a rough idle its been going on for a while and i just cant seem to get it properly diagnosed. Scroll down to find your model range. I wasnt sure about the vacuum lines thanx for clearing that up for me.
I've changed many of them possibly hundreds. Toyotas of that era had a very common problem of the idle compensator motor going bad. In the future I'll probably use other online vendors that don't try to obfuscate their discount process. Could also be worn transmission mounts as well. Started sounding really bad and clunky when decelerating.
Have had a few diagnostic opinions on it, and they all say it sounds like a bearing is going bad in transmission. I've seen coils crack, causing a misfire in one cylinder. It makes me sick to think that a simple thing like that was not resolved easily. If you feel the engine shaking, the crankshaft damper can be a factor to consider when diagnosing engine vibration causes. When your car is in a collision, the axles can be damaged, even when there is no apparent sign of damage. Read them carefully to see if you are experiencing one of the symptoms that is causing car engine vibration. Yes, I do agree that what should occur and what does occur are not always the same.
Replacing your should fix it. They are either out of balance, and would need to be rebalanced, or it is possible although remotely that the tire s may be compromised after hitting a pothole , the belts in the tire may be corrupted. I also would have checked the intake manifold for a leak before replacing it. He ran fuel injector cleaner through once, absolutely no difference. Sorry guys, but I may have mispoke or mistyped myself. I've had it on my car for a while I have a yaris 2008 though.
