Question about 1992 Lexus Es 300

1 Answer

Im having issues passing inspection in TN

Im having issues passing inspection in the state on TN. Im over the CO limit and the HC limit. Ive changed my air intake hose because there was a crack in it, however that didnt help anything. I have a can of carb/fuel intake cleaner but I do not know where to put it (dont laugh, Im just not a mechanical saavy guy lol). Is there anything I can do? Ive spent 1800 bucks on it in the past 2 months and I would like to not spend anymore.

Mcdevito75 here One way that will definetly heip is to cahnge the spark plugs, they burn the air &gas mixture in your enagine that make the emissions. It"ll be a good investment and you should pass inspection with no problems.

    mcdevito75 here, Up date, I almost forgot, your air intake that you want to sray, it should be attached to the air intake hose you changed as stated in your original question, here"s another way to find it, Have someone press down on the gas pedal and release it, step on and release, meanwhile you look for that cable operation under the hood, it"ll be reat close tpo that air intake hose you changed, The unit you see the throttle cable operateing is the air intake, remove that thick hose between the air intake and air cleaner, now start the engine and spray directly into that air intake, iof you can operate the throttle cable you see attached to keep the engine running while you spray, your srayinmg the throttle plate and walls, will help with emmissions somewhat. BUT, Change the spaark plugs, and if it was me I would use ALDOR oil; Burning spark plugs, even if your car doesn"t burn oil, these ALDOR oil burning spark plugs burn everything in the combustion chamber of the engine, after you change the plugs, try to clean the PCV valve, Fill the tank with High test gas, and have your inspection done after driveing the car approx. 45 minutes the highway would be best to have everything in your engine burnt out. Do this and you"ll have a 95% chance of passing those emmissions. Every town, neighborhood has a handy man that can do this waork for you if you can"t and It"s cheaper than a garage, Sorry, don"t mean to run up another bill, but you need to pass those emmissions.

    mcdevito75 here, Once again another tip on the choice of spark plugs, a bit CHEAPER than the ALDOR oil burning spark plugs are the SPLIT FIRE spark plugs sold at Strauss stores, also check with any Auto parts store for these type spark plugs. These SPLIT FIRE spark plugs have a center electrode that is split in 2, so it"s like haveing 2 spark plugs in 1. Your car is high on those emmissions because the air and fuel mixture is not being burnt effectively, increas the burning of the engines air and fuel mixture, and cleaning the engines combustion chamber , (where the spark plugs fire) will reduce emmissions. FOLLOW OUR ADVISE AND UNLESS THERE"S SOMETHING REA:LLY WRONG WITH YOUR CAR WHICH SHOULD HAVE SHOWN UP ON THE LAST EMMISSIONS TEST, YOU"LL PASS EMMISSIONS WITH ROOM TO SPARE, EVEN IF YOU"VE RECENTLY HAD A TUNE UP.

1994 cadillac sedan 4.9 engine will not pass smog. Noxious too high.i replaced egr, erg solenoid,changed oil, still nox is high.hc and co pass


The HC is high because the CO is high, CO is caused by to much fuel being delivered. You will want to check the Oxygen sensor and make sure it is functioning properly. You will want to check the fuel pressures, including rest pressure. We have seen leaking injectors cause this problem. You will want to make sure the thermostat is working correctly also.

First thing to do is check over the sensors that control the fuel mixture as it sounds like you're runnign too rich. This could be due to a faulty water temp sensor. If this is the problem then the ECU (Engine Control Unit / aka computer) will be leaving the car constantly 'on choke' and not reducing the fuelling as the engine warms - so unplug the sensor and clean the contacts on both sides with some switch / electrical cleaner (not WD40) and inspect the wiring for any signs of damage to the insulation especially where it runs over other components and through the bulkhead

If the engine is running well and the state of tune and ignition timing is good (15 degrees BTDC) then most likely the converter itself is bad. Usually NOx readings will go down as HC and CO readings go up, and as a result it is extremely rare for a car to fail an emissions test with all three things if the Catalytic Converter is working properly.

A bad oxygen sensor can also cause a failure similar to this, but will usually cause HC/CO readings to be high (but NOx readings would be low), or the opposite - high NOx but low HC/CO readings. The O2 sensor is located in the exhaust manifold just before the bulge of the catylst and at the point where the 4 pipes join together.

Unfortunately there is no good way to test the Cat. Highly specialized equipment is necessary to do this, however a temperature test might clue you in to one that is bad.

After driving the vehicle for several miles, immediately check the temperature of the converter at the very front and the very rear of the unit itself. The rear should be at least 100 degrees (F) hotter than the front. If the two are close to the same temperature then it is proof the converter isn't working very well.

I have to note though that temperature testing is far from conclusive. I've seen converters that pass test with flying colors but still ended up needing to be replaced.

Aftermarket converters tend to be less effective than factory converters because they are not built specifically for your vehicle. Instead, a universal unit is welded into some exhaust pipes so that it will fit. Generally this isn't an issue, but if you live in a 'green' state such as California where emissions standards are very strict, it could pose a problem.

Keep us updated.

My 92 Honda won't pass emissions at the higher RPM


Sell the car to somebody in FL, no inspection. The state realized it was a total waste of money. Anyway, it probably is the cat, you have 3 or 4 O2 sensors, maybe more. The cat is shot, Just take out the cat, park the car in the street, Call the police in the morning and tell them somebody stole your cat. happens all the time, they go right down the road and cut out 100 cats a night, for $50 each, I don't blame them. The insurance co will buy you a new one if you have the right coverage. If not, you will have to buy a new one, because you can't use an old one. But you can sell the old one on ebay for $50. They are expensive to buy. Hope this helps.

I did not pass smog due to the amount measured for the hc [ppm] test read to high it reads at 711 at 15 mph and 767 at 25 mph what can i do to fix this?


Well, if you didn't pass a state inspection, I can tell you how you may be able to work around it. Depending on state laws for car inspections.....I'll just give you an example: My fiance's car didn't pass inspection, but as long as she paid AT LEAST $200 to try and fix the problem, they HAVE to give her an inspection sticker for the year. We are in NC. Find out the law in your state, if you can't figure out the problem and need an inspection, spend the minimum trying to fix for now.....you'll have a year to figure it out.

Emissions level HC (PPM) too high in truck. How to fix?


Do an oil change with 20W50 oil (or one grade higher) to prevent blow by during the test.

You current oil has HC from blow by though the rings.

Do a fresh oil change will lower the HC.

========
Change spark plugs,wires,cap and rotor if they are over 24,000 miles
========

Make the smog check appointment for the EARLY MORNING. Colder air will help the fuel burn better.

========

Clean or change the air filter and pcv valve.

Clean Mass Air Flow sensor with CRC Mass Air flow cleaner or electronic part cleaner.

========

Do a quick wipe down on the wires and cap to take the moisture off.

========

Check spark plug wire contacts for corrosion.

========

Fill the tank to around 3/4.......just in case your fuel pump is weak.

========

Ran the truck for 20+ minutes on highway before the test.

========

Do not carry excessive cargo on the truck bed.


These are the little things I would do to get the HC and CO down.


Please post more information on the comment window.
