Plus Engine Problems?

[Jesper]

For some reason my right front tire (even replaced) keeps going flat. I've talked to other people and some have the same problem (IS300 05). Also when I try to floor the gas pedal, it doesn't go anywhere, until I let go of it, then puts me into the backseat like a whiplash effect. What should I do? I've taken it down to Lexus Carlsbad and they've told me thats how the car is, and they don't see anything wrong with the tire, but everybody notices the tire going out.

Get it checked by tyre specialist, looks like you got a small hole sumwhere or maybe it not sealed properly

Your alloys may be knackered and leaking through them.

Tyre not sealed to your rim correctly - due to either the tyre, rim or poor fitting / sealant used.

i think if it doin it after tyre replaced you need to look at the wheel, maybe a hairline crack just enough to let air escape slowly. or there could be perosity in the wheel. (tiny holes from the foundry/ poor casting) maybe a new wheel or get it inspected by a wheel repair shop for leakage.

For the tire, make sure that the rims are in good shape, otherwise the tire will make a poor seal. Usually when you get new tires put on, they grind or clean up the rims, make sure that they did this.

As far as the pedal goes, I imagine the lexus has an electronic accelerator, if you push down too quickly, the sensor doesn't pick up the full motion, my cadillac does this a little bit too.
