The check engine light on my car was on for a few days, i did the trouble shooting of making sure the gas cap was propery tightened. i then took it to Auto Zone to have them do an engine diagnostic. they said all was fine and the light shortly went off. the car was fine for about two weeks and the light appeared again when i went to get the oil changed they said the engine was fine. the light went off a few days ago the message board stated the engine service required as well as something about the alarm. the car started buckling on the road i stopped driving it when i got it home. two days later i turned it on to move it off the street and the message is no longer there

99% of the time, the gas cap wasn't tightened properly, or is leaking. Make sure you twist it tight and it clicks a few times. If the "Check Engine" light stays on after a few days, buy a new gas cap. Again it may take a few days to clear.
Not likely.... But as you just put fuel injector in make sure your fuel cap is tight cause if its not the computer will detect a evaporation leak in the gas tank. So tighten the gas cap and drive the car for a few days & see if the engine light goes off .. If not get the computer scanner to see what's going on
#1 problem is a loose gas cap or driving with the gas cap off. If this is the case then tighten gas cap and the light will go off in a few days. If this is not the problem then you will need to have someone read you trouble codes. some auto parts stores will do this for free.
Because your vehicle is a 2008 I feel it shouldn't be anything to pressing but still take some precautions.
What alot of people don't know is sometimes if the gas cap is not put on tight enough a little air might get in or your gas pump might have to work a little harder because it can't get full vacuum pressure with the cap slightly open. these are not major issues.
these are reasons why your check engine light comes on. It happened to my 2005 Buick Rendezvou We had the check engine light on for a week. The car never shuttered, stalled, delayed starts it ran perfectly fine. I took it in to check engine light their computer showed that it was the EVAP system which is the heating and cooling system I would have to get it checked for leaks or do a static check for leaks.
This didn't look good but then one day I had done some work for a friend told him of my problem he told me it could be my gas cap. The next day I asked my wife if the gas cap was working on vehicle it actually was broke I replaced gas cap and the check engine light came off.
Now with this story (which is true) don't assume every problem could be this. But if you are not noticing any stalls, delayed starts, shuttering anything out of the ordinary check the cap at times to make sure it is closed.
If you keep on having light on and replaced cap or made sure was securely on then take and get it checked out.
The P0141 code points to the O2 sensor heater circuit. It could be that there is a short in the wiring to the O2 sensor or it could be that the O2 sensor heating element itself is bad. The code is for O2 sensor Bank 1 Sensor 2. Bank 1 means its the O2 sensor connected to the exhaust pipe that runs to cylinder #1. Sensor 2 means that it is likely the O2 sensor after the catalytic converter on the same exhaust pipe.
