My xB has 32,000 miles and has only recently started shaking at idle when in drive. It's bad enough that the dash is starting to make some noise.
Could it be a broken motor mount? It runs and drives OK (although painfully slow automatic.) Any advice would be greatly appreciated.

This might sound really crazy, buy try changing your oil and putting in Mobil1 5w30. I didn't have a chance to change me oil for a few thousand miles and mine would vibrate really bad at idle. I just changed it the other day and have not have the problem since.

*shrug*

I second the Mobil 1 comment. Expensive but my engine runs much smoother with it.

Scichologist

I'll try it. It doesn't sound crazy at all. I can tell when it needs an oil change. Any friction slows the car down. Thanks.

let me know im quiote intrested

get a really fine girl with a nice set a t1ts and have her sit next you... then let the car idle and shake - problem solved!

lol i like your advatar larry its halerius. i saw one like that but it said my vvti just kicked in, i laughed so hard at it it couldent be more wrong lol.

What is it idling at if the idle is below 700 rpm it will shake and there were some of the last body style Camry's that would shake at idle but they were idling about 500 to 650 rpm.

I have tried Mobil1 5W30 full synthetic. It is louder than ever! I drove from Denver to Los Angeles at 4,000 rpm for 17 hours is so bad my ears were ringing. Then from Los Angeles back to Denver I put in Royal Purple 5W30 full synthetic and it is a LOT more quieter than Mobil1 5W30 at the same RPMs.

I am not trying to sell Royal Purple. I'm just saying try something else like Castrol full syn or Valvoline full syn or any other syn.

I'll second that Royal Purple claim. Smooth as hell, but a little pricey.

I get vibration too but it mainly comes from the gas pedal, puts my foot to sleep on long trips like yours

mobil 1 sucks, i use to use it and it made the engine very noisy, and tick at idle, when you have low milage and your car is making that kinda noise people tend to look at you, i use castrol 5w30 synthetic and it went away

Scichologist

Well I'll change the oil this weekend and see. Probably won't use synthetic b/c let's face it, Texas is a big state and the miles just tick away. I still need to check the idle rpm. It doesn't vibrate all the time, mostly when it's cold.

Walmart - $25 for a 5qt bottle of Mobil 1 5w30 syn.
Toyota - Oil Filter $4-6

synthetic last longer so its kinda worth the extra dollars, then you wont have to change the oil as often either maybe like 4 or 5K thats what i do and i have no problems

low_down_xb

i forgot that mine used to to this, you can just adjust the idle up a little after is hot and that will fix it too

ifeldwn02

i just dont trust an oil like royal purple when they not to use it until the motor is broken when mobil 1 comes from the factory in alot of high dollar cars and i have never had any problems in the past running mobil 1 just my 2 cents

Spiderbox

i think i have that problem too. does the idle fluctuate 100-200 rpms at idle? i hear the engine shudder and then the rpm fluctuate for a few seconds from time to time at idle.

i have no idea what it could be. all i know is that its NOT the engine oil.

My Echo shuddered at idle/startup when it got around 80,000mi and switching to Mobil 1 from a synthetic blend helped.

Scichologist

no fluctuation. It idles around 7-900 rpm best I can tell on the microscopic guage.
