1994 Lexus SC400 Q&A

1994 Lexus SC400 Question: car shakes when accelerating (sometimes)

My Lexus sometimes shakes when i accelerate, my steering wheel does not shake at all, i just got my car balanced, so i don't know what the problem is -
Answer 1
Has the Check Engine light come on? I wonder if the shake you are experiencing is engine related. I wonder if a coil (your car has two), or if a spark plug or spark plug wire has failed. The ignition system is under most pressure on acceleration. -

my check engine light has always been on, the shop said its just the sensor though.. could it be anything related to the wheel? axle? bearing? rim? because i hope its not the engine itself that would be a problem -
Comment 2
Sorry I am late in getting back to you. The check engine light being on should not be related to the "shake in the wheels" a wheel bearing or suspension/steering related component. A engine running rough and misfiring or experiencing an ignition failure will cause a Check Engine Light to come on and set a code. A repair shop have told you it was a sensor failure, was it the heater circuit in the Oxygen sensor that failed? -
Answer 2
Your drive shaft is simply worn out. It is cuased from harsh acceleration. There is a rubber doughnut that is gettting old. It only cost me 100 bucks to get it fixed. Grab a driveshaft out of a junkyard. -
Answer 3
Don't drive during an earthquake -
