About 2 weeks ago, codes 2187 and 2189 showed up in my 2007 Santa Fe 3.3L, just over 80k miles. I know they are System too lean at idle bank 1 & 2, but not sure where to start as far as figuring out where the problem is. I did buy some electronic's cleaner and pulled out the MAF sensor and cleaned it. After I re-installed it, then light went away for a week or so. It has popped back up again today. The vehicle is running fine and seems to idle fine. I have noticed that the gas mileage is lower then normal. I usually see 24mpg, but it has dropped down to around 20mpg.
About a month ago, I changed the spark plugs, put in a new air filter, along with an oil change. Not sure if the codes are related to me changing the spark plugs (which seemed like taking half of the engine apart), not sure if I may have nicked a hose or missed putting something back.
Im not opposed to replacing the MAF sensor, but would hate to replace it just to find out it was a $5 hose. I did spray around some of the hose's to see if the engine picked up any of the fume's from the electronic cleaner, but didn't see any change in the engine, but then again, I may not of sprayed near the right hoses'.
Any idea's on where to start problem solving, or is there anyway to test the MAF to see if that's the problem?
Thanks
