Failed smog my car failed smog inspection it failed the part were it said emmissions they said the numbers were to high

First I recommend changing spark plugs, air filter, and change the oil & filter. If these are dirty or fouled up it will kill your millage and help to fail smog.
You can reduce both NOX and CO emmissions by adding denatured alcohol to the gas tank. Run it down to a bit under 1/4 tank and add 1 1/2 gallons. It makes the engine run a bit rough, but really clean.
If you still fgail SMOG then you need a new catalytic converter.
I used to "trick" my 86' with alcohol, but just rebuilt the engine so I put a new Cat on it. It passed emissions with WELL BELLOW numbers.

Good luck.

NOX is high coolant or engine temps
& egr issues

Lots on the internet to study on exhaust gases
& the reason they fail inspection or are too hi

if you are failing emmissions test your evaporator canister is expired replace it and then you and your car will get a green light

Hi,

Code P0741 = Torque Converter Clutch Circuit Performance or Stuck Off. This relates to your transmission only and has nothing to do with Exhaust emmissions.

If failed smog test, there must be an issue within your emmission system, e.g. sensors etc

You will need to have your codes read again, or have your vehicle properly inspected.


Cheers,

CHANGE SPARK PLUGS AND WIRES .AND AIR FILTER.IF YOU SEE CHECK ENGINE LIGHT FLASHING ON.CODE SCAN SEE WHAT FAULT CODE YOU ARE GETTING.

P1396 Glow plug monitor fault, bank #2 One or more glow plugs failed or circuit fault

You either have one or more bad glow plugs, a disconnected harness under the valve cover, or you have a problem with the glow plug module. This code is only for californial emmissions trucks, which are the only ones with glow plug modules.

mcdevito75 here, BEST BET let your local shop run a scan on your cars computer, 1 or more sensors that control engine emmissions may be bad, if so you"d never pass smog inspection. Sorry.

clean all engine breathers, engine flush, then change oil and oil filter. this should help dramaticly

change oil and filter put a emission cleaner in fuel

Emmision is the fumes produced by your exhaust. Do a tune up on the car and have it checked for exhaust leaks. Spark plugs, Wires, oil change if needed, O2 sensor, Air filter and such thing as this should put it back into order. Which state is this? If it is california then you might want a professional opinion because they no more about smog canisters and stuff likethat. But tune up should do it.
