    I bought this preowned RX330 of 2004 2 weeks ago. When I purchased the SUV the dealer gave me Safety and emission test reports. I have faith that this SUV must have passed the ET. However I felt nthe difference in the smell of the gas. I will look into your advice too. Thanks

If that does not work, which it probably will. you may want to have the catalytic converter checked. get scanned at Autozone for free.they will give you a code number. Cleaning up the system will remove deposits that are making it smell bad.

Run fuel cleaner through, do a tune up replacing these items: spark plugs, wires, distributor cap/rotor. This will make sure you are firing all cylinders and no unburned exhaust gasses are escaping. Also, a bad oxygen sensor will make you fail your smog test. Most importantly, ensure your drive your car at highway speeds for around 30 min to ensure your catalytic onverter is hot. Cold cats will fail you every time.

the smell probably came from a wire that is shorting out-maybe when the headlights are turned on-look at the wires right behind the headlight-look for burned or bubled insolation on the wires-cheers Denny

I have had a fuel leak (gas not liquid) in my 95 TownCar for about two years now. I've taken it every where, even the dealer, fixed every possible part, yet I still have the horrible smell. The entire fuel...

if you smell it, its leaking. Do you keep it full all the time? if so you may not be able to get it not to smell, if the canister is saturated. A shop can pump smoke into the system and find any leak, Find a shop that does emission inspections.

Constant smoke from tail pipe.

If its smoking that bad you should be able to tell if its oil or antifreeze by the smell, stand behind the car as its running, if its white and you smell a sweet smell its antifreeze if its blue and smells like a oil refinery its oil.

At 167,000 miles there will be wear on the piston bores and rings this means you will be burning off oil even during normal running

Standing test is to make sure that the car is in park and get someone to really rev the engine for a few seconds let it die down and do it again repeat this 6 or so times and I bet you will see a thin blue smoke coming from the muffler
