No body would know without Scanning the computer, Take it to Auto zone and they will scan it for free and tell you the code, because when the check engine light comes on that means one ore many problems were detected. Good luck

Why to auto mechanics suggest replacing bad catylitic converters with straight pipe? Is this not anti-environment?


Yes, and it is probably *******. Also, your engine light will not go off anyway, so why not just leave the bad converter on the car? Makes no sense at all.

Check engine light on and flashing, car shaking, all of a sudden


you have a bad engine missfire. a flashing check engine light means you are in danger of damaging your catylitic converter and you should scan the car. most causes of missfires are plug wires and or coil pack.

Where are the four o2 sensors on the 2006 lexus es 300 located, are they all different models or all the same. I believe they're two on top and two on the bottom.


usually in pairs two of one type threaded into exhaust before catylitic converter and two of another type threaded into exhaust behind catylitic converter(looks like little muffler in exhaust close to engine.)

Car engine is running rough sounds like a miss the what I believe is a catylitic converter connected to the exhaust manifold on the drivers side gets glowing red I was told this is do to it being clogged...


Yes it is true, I believe there are 4 cats on that car. burn the correct fuel in it and it will run better and not clog your cats, that car takes premium gas.

Check engine light showing - was told by dealer that both catylitic convertors need to be replaced


Your check engine light could be coming on for numerious reasons. Your catylitic converters could be clogged, but it could be O2 sensor or something basic like any little sensor cars have now days. I've heard of new cars check engine light come on just because of the gas cap not tight, lol. You can take it to autozone and tell them your light is on and they will run a diagnostic check on it and it will tell you the problem if it's listed on their machine and it's free so it wouldn't hurt to try. But your light has to be on for them to read why, when you go.

The best thing to do is go to an exhaust specialist, who can check the catylitic converter and also the oxygen sensors. You will need to replace these items if they are at fault. Hope this helps

Car speed not exceeding 120km/h


sounds like catylitic converter is blocked. unbolt exhaust infront of catylitic converter, and try it that way

Catylitic Converter is not fully consuming unspent fuel


 This is an expensive repair...catalytic coverters need replacing if everything else checks out on the car.  However, a loose oxygen sensor lead would make the car running rich
