What causes high CO readings in auto emissions test results?
High CO is a rich air/fuel mixture. Nothing else.
What filter should you use to reduce carbon monoxide emissions?
carbon monoxide is a rich indicator, if you are producing too much, you have a fuel system problem.
What is mean by air fuel ratio?
the ratio of the amount (mass) of air to fuel. Ideal is 14.7 lbs of air to 1 lb of fuel to completely burn air the fuel. A slightly rich raitio of about 12.5:1 car produce more power at the expense of emissions.
Why does a 1991 Honda Civic LX exhaust smell like rotten eggs?
Malfunctioning emissions system. Get this repaired. Engine probably running rich from a leaking fuel pressure regulator. If there is fuel in the vacuum line the regulator is bad.
1993 vortec 4.3 runs rich?
Need to check fuel pressure regulator, and it could be the MAP sensor making it run rich. Is the check engine light on???? If it is have engine scaned with engine scanner so you can read the codes, and see what is going on with the emissions.
What happens to a vehicle if the OH2 censor happens to be cut and how long would the damage take if any?
If you mean the HO2 (Heated Oxygen Sensor), then that works to tell your car's ECM how rich or lean the engine is running. The ECM uses that information to adjust the fuel ratio to keep the engine's emissions to a minimum. If the Oxygen Senor is not functioning, the ECM cannot tell what the engine is doing and goes to a default, rich fuel mixture. An overly rich mixture will decrease you vehicle's fuel economy and cause damage to your catalytic converter.
Why won't a 1992 Chevy Cavalier pass smog excessive fuel consumption running too rich 1300 instead of 100 what should be checked?
Oxygen sensor. Fuel-to-air ratio should be 14 to 1.
How to fix code p1441 on Chevy tahoe?
general consensus that the PURGE VALVE SOLENOID is to blame. Of course it is an emission control nonsense....but nevertheless, needs to be resolved to pass emissions and to keep the SES light off. Some of my research states that fuel economy will suffer as it can pose a RICH running condition. I'm not certain if that is indeed correct, these vehicles are not known for great economy.
Can new spark plug increase hc emissions?
not really.new spark plugs should help to decrease hc emissions hc emisions are caused by unburnt fuel which is usually caused by faulty spark plugs or faults in the ignition system which would cause the engine to misfire creating a rich mixture ie high hc (hydrocarbons)
What problems may occur if you overfill your 1996 Mercury GM gas tank?
FUEL WILL BACK UP INTO THE GAS TANK VENT LINE CAUSING THE COMPUTED TO THINK THERE IS A RICH CONDITION AND TURN ON THE SERVICE ENGINE SOON OR EMISSIONS LITE
What is the relationship of a pseudoscorpion and a cerambycid beetle?
The pseudoscorpion demonstrates phoresy in respect to the cerambycid beetle. This means that the pseudoscorpion relies on the beetle to assist it in moving away from a location to a new one, effectively allowing it to travel unmolested to a new food rich environment.
What is it called when there is too much fuel in a fuel and air mixture?
A rich condition.
