It's probably a clogged catalytic converter.

SOURCE: Fuel running rich, blowing gas out of one side of exhaust

One of the fuel injectors is leaking.
It is sending gas out even during the exhaust stroke.

You may be able to "hear" which one it is by using an auto stethoscope ($12) (like a doctor uses) and listen to each one of the injectors.

replace the faulty injector ... or use a can of fuel injector cleaner (name brand, not store brand) ($8).

Any auto parts store (Like AutoZone) will have it.

Hope this helps, soon!

SOURCE: strong gas smell coming from my cobalt at all times

Look in the back of the car. The fuel pump lines like to break. You will not be able to see them, but you will smell and see that the fuel tank is wet. Call your local dealership, have you vin # and milage, ask them if it's covered by warrenty.

SOURCE: run rough at low speed

Possibly there is to high of a mixture of gasoline going into the cylinder. It might be a computer problem, the dealership/garage with a Tech2 would be able to tell you for sure.

SOURCE: Fuse Box ( cover) diagram for a 95 Lexus LS 400 is missing.

check the wiring harness beside the hinge that moves when you close the trunk.i have seen the wiring get pinched and the ground gets broken. the tail lights have separate left and right side fuses.get a test light,and with the ignition in the on position,there should be power on both sides of all the fuses.the atc type have little test pins on them.ground the test light and put the tip on the fuse.if there is power,the light will come on. if a fuse does not light up the light on both sides,it is open.since the fuses are see thru,it is apparent if it is blown as the metal inside will be burnt.

What is wrong with My Lexus LS 400, reverse gear was burnt but was fixed. After repairs it started consuming much fuel, raw fuel comes out of the exhaust, the oil was changed it was mixed with Fuel.


You really need this fixed fast for if you have raw fuel coming from your exhaust your catalytic converters must not be working. If they were working they would be running a extremely high temperatures and be a fire hazard.
You most likely have damaged exhaust valves causing this problem, a compression test will confirm if this is the case. The other possible causes are bad injectors, coils, spark plugs and ignition timing.

Large thump noise and wouldn't start. Then got it started and car was missing really bad and white smoke coming out of exhaust when I accelerated


Your car has what is called a blown head gasket. The thump you heard was the coolant in the cylinder. The white smoke you are seeing is the coolant leaking into the cylinder and burning. that is well is what is causing your rough running problem. I hate to be the barer of bad news but this can be a costly repair. Usually around 1200.00.

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.

How many mile can u tipically get out of a 93 lexus 300 before itsnot worth resale value? i was in the market to buy a lexus but it has 210,000 miles on it. it runs excellent! the purchase price is $2500...


AT 100,000 MOST PEOPLE ARE LEARY TO BUY EVEN A LEXUS, AT 200,000+ THE CAR ISN'T WORTH MUCH, I WOULD OFFER $2000.00 IF THE CAR IS REALLY NICE, BUT STRONGLY SUGGEST U ASK FOR SERVICING RECORDS LIKE OIL CHANGES AND HAVE THE CAR INSPECTED BY A LEXUS DEALER.

Backfiring, rough idel


I would check the exhaust pipe a little closewr. White smoke can also mean a blown head gasket. Check the tail pipe to see if moisture is present. Also check coolant level. A blown head gasket can also cause related problems.

Running rough


Hi, runing rough can be caused by several things, you can start by checking the simple ones first, fuel filter, air filter, spark plugs, add a good injector cleaner and leave the car runing for some twenty or thirty minutes ,if it dosnt change,you may get the injectors cleaned by a pro shop.....good luck....
