please help me my car is up for inspection in two weeks, be specific in your answers
I chuckle whenever Check Engine questions arise, because inevitably half the answers automatically begin with, You need to replace the oxygen sensor. A lean condition is usually caused by a misfire, either through a faulty spark in one or more cylinders, or a fuel delivery problem, either through a clogged or malfunctioning fuel injector (causing the fuel to atomize improperly). Both conditions will result in an incomplete burn of the fuel/air mixture, causing the presence of excessive unburned oxygen in the exhaust, tripping the 'lean condition' code. Very rarely will the fault be the O2 sensor itself, and even then, the code for that will be, Oxygen sensor stuck in lean (or rich) position. The earlier suggestion of switching the sensors is a good one, but for the do-it-yourselfer, pullinng O2 sensors can be a real PITA. Unfortunately, this means you will have to do some troubleshooting to find the fault of the problem. Start by running a decent fuel injector cleaner through your motor if you haven't done so lately. BG-44K or Chevron Techron are good choices. Pull the plugs, as well, to ascertain their condition and to rule out the ignition system as a culprit. If neither of these things clears up the problem, have the car looked at by a competent mechanic. Just automatically replacing the O2 sensor when the 'check engine' light illuminates is what I call 'shotgun mechanics' - that is, firing lots of new parts at the car until it is fixed. It's also a ploy used by shady repair shop into getting you to buy up to four O2 sensors at as much as 150 bucks a pop.
How can we be specific when you didn't bother to tell us what kind of vehicle it is? Honda? Mazda? Chevrolet C3500 HD? Could be most anything from a bad mass airflow sensor on up. Go to the local auto parts, and get a can of SeaFoam, pour it in the gas tank and see if that helps. If not, have it looked at. Too lean bank 1 is very general.
TAKE IT TO A MECHANIC OR PAY THROUGH THE NOSE FOR YOUR EDUCATION. be specific.ARE YOU A JOKE??.WHAT KIND OF FRIGGIN CAR!!! WHAT YEAR!!!! TO CHECK THE OXYGEN SENSOR REMOVE BOTH SIDES AND SWITCH THEM AND REINSTALL THEM IF YOUR CODE CHANGES TO SYSTEM TOO LEAN BANK TWO YOU WILL KNOW THAT OXYGEN SENSOR IS BAD.
I like. Ensure secure recording, stored off site, that can be accessed securely with ease by the user. Also, consider IR lights instead of visible, unless your goal is deterring.
