im getting two codes after installing a cold air intake on my v6 2.7ltr Hyundai Tuscan, PO171 PO174, both are related to fuel too lean? ( according to the Pep Boys store). I checked the connections for airleaks and all is tightened still.The car is running goodwhat should be my next step? Please note I am not a car mechanic at all. and thanks.
The pressure rating on the side of the tire is the tire manufactuers maximum pressure rating for the tire. The Door Panel rating is the car manufacturers recommended rating for your vehicle with the proper wheels and tires. Use the car manufacturers rating (door panel) since that is level needed to make the car ride and handle the way it was intended.
i am in agreeance with Vip. why would someone go with the rating of the door if you have after market tires that show what the psi is for that specific tire. with that much of a difference, it would be like riding on a flat tire.
door panel is what is recomened for your car or truck what is on tire is max air it should hold safey an dreally its up to driver to adjust the air by tire wear it depends alot on if one is hauling loads or towing alot or just one person riding in it but door panel is the best starting point an dafter that you have to adjust more or less by watching wear here is a great video on tire wear
once you put in the intake you replaced the air bypass to the engine and the maf sensor is sending incorrect air gasoline information. to the workstation. The maf sensor is extremely gentle and can be dealt with intently and wiped sparkling with touch purifier. The compressed air and tough dealing with might have broken it additionally. a sparkling sensor won't remedy the basis situation brought about by utilising the hot intake.
a cold air intake creates a more consentrated charge of air and fuel (ie if you put a balloon in the fridge it shrinks due to the molecuels gathering closer together). in this situation, you are adding more air (oxygen) into the combustion mixture. more fuel can be fit into this mixture to cause a bigger bang and therefore more power. the optimum mixture is 14.7:1 air/fuel. ie 14.7 parts of air to 1 part of fuel. if you allow more air, you will offset the mixture ratio and possibly cause the emission equipment (check engine light) to come on. you will not notice any real performance problems with such a small change (that is why the car seems to act fine), but your computer knows it. first, make sure all the sensors are connected properly. second, you can buy a computer programmer (ex. Superchips and the like), to reprogram your ECM to accept the changes you make. They run about $400 though. either that or you have another emissions sensor bad. ie an O2 sensor, air flow sensor, etc. going bad, and it's just a coincidence.
