I recently buy Toyota Passo 2010, it has lot of issues, after solving few its still give vibration, special around 40 to 60 km speed, it also give vibration on startup but when driving on 40 to 60 km speed it give wired kind of vibration and when give more accelerator vibration vanish but when speed reduces vibration came back and also give jerks and feels like engine is stoping like engine normally do in first gear. things which done so far are: cleaning of throttle body, spark plugs, engine oil change, air filter change, exhaust silencer cleaning, after doing this car pick has been increased but vibration is still there, please share you knowledge on this and i hope will find something solve it. Regards Khalid
check engine mounts, ( where the engine is bolted to the chassis ) .
Have checked that its ok
for that "Special" vibrations during certain speeds, get your axle inners checked...they are likely the problem.
Seems wheels are not balance.Do the wheel balancing from some good place and then feel if the vibrations are still there.
which engine oil you are feeding?also have it check by some good electrician to make sure its current is ok.
Wheel balancing done, but result is same, i also replaced fuel injectors but doesn't effort
Hmm thinking over it...
Was vibration present in the car when u bought it from Day 1...?
yes since i purchased
Ac on or off??
both, even more when AC working
From which city you are ?
Well I had the same problem. Checked out the sensor and the brake and accelerator pedals, then it worked fine

Vibration is in almost all Passo. It is due to clogged Catalytic Converter. Go to any 3S Toyota Dealership and get your car scanned by computer. Get the Catalytic converter clean and you will be all fine. Please update about the progress.
so what solution did we find on this vibration issue?
Hi, no solution bro, i have changed compressor bearing, generator bearing, now mechanics are suggesting to change gearbox.
Its very hard to find a good mechanic
Hi,Went and saw the mechanic, he say 80% the problem might be bcoz of the engine mounting. He even demo to me the problem.
should i change it ?
hi, yes, you should, if mechanic has identified that engine mount is causing issue.
It's very easy to check engine mount, normally top engine mount cause this issue.
Best of luck.
This problem of Toyota Passo is common in many passo when u reach speed of 50-60mph it is caused by missing in engine combustion chamber, it can be due to lack of fuel supplied by nozzles, or spark plugs (all Passo need long reach spark plugs) if u use other plugs depend to have missing in your car. Also oxygen sensors are really mater on this missing once u reach around 50-60mph, also throttle body cleaning. Plus other sensors check by obd2
Check ur mounting (where the engine is mounted). Vibrations mostly like to happen when mounting leaks. From above it looks all well. But when u open it then u can see that oil have leaked from it and it's broken. Check it, hope it will help.
