All calipers, pads and rotors are new and just put on. I jacked it up after driving it for a couple minutes and could barely turn the tires and all the rotors were really hot.

iwant change out the battery cables first ...the ones I bought have only one spot to make connections on each post ....but the Lexus 300 rx 1999 has two positive wire that are connected to two separate positive connections on the battery connect from the factory.....Question I join both Positives on the connector ....or do they need to be separted buy the type of battery connector that has the two connections?

I replaced the starter yesterday.

While on my first roadtrip, post rebuilt tranny, I could feel a slight hesitation in speed. It's almost like the car had a hiccup. There are no warning lights on, I had my fluids checked before I left. I'm slightly concerned because we have a 600 mike return journey home today and it's just myself and my mom.

I just purchased a 2000 Lexus rx300, it sat for close to a year, I put a new battery in it, it starts right up, idles like a new car, but when I went to drive it, if u give it gas it spits and sputters and won't go anywhere, let off the gas and it idles just fine.... Has anyone had a similar problem??? This is the first Lexus I've owned, it could be numerous things, I'm mechanically inclined but was hoping someone had similar problems and new the solution..... Any info would be greatly appreciated....

The audio is only working intermittently. It is getting power, and the fuses seem to be okay. The radio, cd, and tape players act like they work, but no sound comes out, not even crackles.
Also, possibly unrelated, but the back right door lock will not work with the power locks.
Any ideas on what what this might be, or how to fix it?

The locks on the SUV have to be locked manually. None of them will open or close with the automatic unlock/lock function on the key. The only lock that works correctly is the tailgate lock. I have looked on other forums and it seems this is a common occurrence with the 2000 RX 300.

On road loose metal nuts bolt sound. Shop said bolts loose. Noise still there I'm afraid to drive. What all is taken loose or off to replace rear valve cov gasket. Going back today do I just ask them to recheck everything they disconnected or took off? Help please someone who knows not from state of Mississippi. They were hush hush on the loose bolts. Felt like what else??? Please I would appreciate some helpful advice. They didn't do any ck for codes. I don't have over $900 again.

I drove to a gas station got gas then it wouldn't start. my Lexus has 125000 miles on it. I recently replaced both knock censors.

I ck it have following cods p1130 air/fuel sensor ,circuit bank 1 sensor 1 MOD 10 , P0300 random mis Fire dectected pending, P0303 cylinder 3misfir decked landing MOD 10 ,P0305 cylinder5 mis Fire dectected MOD10 ,P1130 air/file sensor pending MOD 10. I have replaced all spark plugs spark plug ignition coils also replaced O2 bank1 sensor1 but still have all the above cods

my rx300 was involved in a single car rollover accident, with what appears to be little to no structural damage as well as obvious dents and cosmetic issues such as pushed in windshield and no side view mirror, is the car worth putting the money in to fix?

doesn't do it all the time and when it does act up od does not work.keeps throwing codes like miss fires,coolant closed circuit and more.had maf replaced,coolant sensor,timing belt and coils and plugs.acts up more under 50mph.will be driving and just like you turned key of then on quickly.every thing else stays on like radio and electronics,but motor just cuts out.spent 2000. already.

What should be the reading of O2S B1S2?
The readings I get, at idle, temperature 190*, vary from 0.000 to 0.010 to 0.770.

The car while driving sets P0125 code first then later will set P0172. While the car is sitting still, at idle it only trips the P0172. However, leaving idle for another 5 to 10 minutes it starts setting the misfire codes (P0300, etc).
