Low RPM Vibration

[Suavo]

Hey Guys. Sorry for the double post, I know there are some threads up on this already but they're old. i bought a '98 corolla ve with 70k miles on it from a friend for $1k. It was parked in his driveway for 4 years. did all the necessary replacements (tires, oil, plugs, etc.). The car runs great except for a vibration at low rpm.
i only hear it if i accelerate hard from either a full stop or slow roll. its not consistent though. sometimes you hear it sometimes you dont. any ideas?

[ilovecorollale]

lose suspension bolt/nuts, possible warped rotors, loose calipers, axles, axle nut, bad tie rods, and could be wheel bearings too.There could be a ton of possibility that causes it.

By the way is it auto or manual? And did you balance tires?

[Suavo]

its an auto. just before i bought the car in july of last year, he had taken it for a alignment not sure if they balance them.

Or it could also be a bent rim.

+ 1 Besides tires, a bent wheel is overlooked alot. Look for any dents in the rim where its hit something.

lol. my rims look like shit but if the vibration is coming from my beat up rims, wouldn't the steering wheel shake like crazy?

[ilovecorollale]

Yes, Probably like crazy but during highway driving around 50 and up mph.

Is the vibration following engine RPM or wheel RPM?

[Suavo]

Sorry for the really late reply. Have a new baby girl now. Um i would say engine rpm. i Noticed that when in low gear the car takes off like a rocket with no weird noises or vibrations.

I don't think it's the rims. It might be because you have very old/bad gas in your tank. I would put higher octane fuel with an injector cleaning product.

I actually had the fuel injectors flushed in June 2011.
