The Cats dont last forever, THE CAR WILL... but the cats dont , mine is fine now just coming up to 140,000 miles and drives like new.

Wow now that is handy .. thanks for the link PCM

The main thing I hear in my RX is my keys banging on the dash just under the ignition switch, Im not sure but could this be an annoying problem the car designers have not thought about ? it was the same on my old GS or am I just too picky, ok a small bit of sticky pad will do the trick or take off all the other keys on my keyring. Is it just me ?

The CO levels were the same but the car runs that little bit better so Cataclean was worth the money, The guy at the test station said he see alot of this Cataclean dose work for alot of people and not with others its all down to the fault he said he has changed Cats that have a small hole inside so some gases are by passing the cat, Cataclean cannot fix that... Em makes sence. The car does run very nice, the new cats are on there way.

Sunday I was near Halfords and thought Cataclean as people on here have said its worth a try, so I had a 1/4 tank payed the £15.99 put it in and drove 20 miles and then some more Monday and the car seems a bit better. Today Tue went to the test station for a em test ........**** **** ***** still the same **** *** but yes worth a try Just ordered two cats from the states £375 inc plus £60 to fit. Thanks guys for all your help, I do like this RX the ride is better than my old GS,s mk1 and mk2 even the seats are softer. thanks all.

It has a new air filter and the sensors have been changed at some point, I spoke to my mechanic he says the sensors have tested ok he says if after the cats have been changed and it turns out to be a sensor he will sort that for free, cant ask for better than that. So Monday I will order the cats from the states. http://www.ebay.co.uk/itm/Catalytic-Converter-Direct-Fit-Rear-Y-Pipe-New-For-Lexus-RX300-Toyota-Highlander-/191495428659?pt=Motors_Car_Truck_Parts_Accessories&hash=item2c96045a33#vi-ilComp

Thanks Guys, Just had another test done at another station and the result is the same well almost, CO levels too high about twice the max limit. I have been thinking about what CollinBarber said "he is often right", about the MAF sensor Ive cleaned it twice, when the first test failed, it failed on "Natural idle test" CO 0.674 limit 0.500 .. I cleaned the MAF and had it tested again Now it passes the Natural idle test CO down to 0.213 but still fails on the first and second fast idle test still high CO. Im thinking about replaceing the MAF sensor ebay have them for £26 (after market ones) to see if that changes anything. The Cataclean might work if the CO levels were just over the max limit but mine is 2x the limit. Thanks guys for your valued input.

Good idea may come to that.. Im having a e test tomorrow from another station only costs a £10 ill let you know.

Thanks Guys for your input, and I agree with you all, It is my local car repair man who I have known for along time, and he uses our local mot station he says the sensors are switching ok and it can only be the cats or a cat, but yes I agree strange no error lights so no codes, and it is only the CO levels HC is ok and yes I will get a second test done before i do anything, I will let you know what they find. Thanks

My RX300 Mk 1 02 has failed the mot ... CO levels too high Fast Idle Test..Actual value 0.766 Max Limit 0.300. Second Fast Idle test.. Actual Value 0.530 Max Limit 0.300. she passed on everything else. The guys say "Needs new Cats Mate" ... they seen sure its not sensors. I can get Catalytic converters for this car front and back from the USA for £365 with post and customs. Is this a good price as here in the UK they are alot more and is there only two cats or is there a 3rd. Any help anyone can give on this would be nice.....I dont have any engine check lights on and she drives very nice. Thanks guys.

Sticking brake caliper on passenger side.....maybe.

So it was the intercooler that failed not the gearbox.......until the coolant got into it.

A LS430 Gearbox failed..... this has got to be a April fool thing....right ?

No it was not him driving,.. wrong shaped head.

They might use some shots of him driving from old seasons, If they do I will notice, but yes your right about the copper.
