Hi everyone,

I am new to this forum and would really appreciate your help !

Got my Rx330 2004 model (used) with 20000km's . Now on my 30000's , it stopped responding as it used to. When I first got it, the car used to respond like hell. Very fast accelerations, real power could be felt. Suddenly, on an early morning, I start the car and could feel the exhaust sound coughing. When I put it on reverse, the whole car starts to shake, until i push the accelerator.
Put in on Drive (D), the car stops shaking, but as soon as I press on the accelerator, the exhaust again does the same coughing sound during the 1st gear, and "loss of power" can be felt.

I have checked the exhaust with a mechanic, and it seems to be perfect !

Just cant figure out what the problem really is !

Please help me on this !

Please let me know if you need any details !

 

Are you getting a Check Engine Light?

Where does your RX stand in maintenance? What is the warranty situation and what does the dealer say?

You can try disconnecting the battery for 1/2 hr or so. [Caution: you may loose your presets]


The root cause seems to be the engine and the exhaust just muffles the engine sound.

Yea .. I am getting the check engine light ! unfortunately ! But I only get it for some time, and after 10 to 15 min it disappears !

Forget about warranty and dealer as the car is imported ! !

Do you think it has anything to do with the spark plugs ?

Thankz for your help !

 

Dirty gas or tank, cat plugged, fuel pump going out.

My car would start then sputter and die, turned out to be a bad fuel pump.

 

Some local dealer or shop should have an obd-II code reader and can pull the error code from the vehicle. The codes will tell you what is wrong.
