Question type: General

I have a 2005  chevy  cobalt 2.2 engine, it has 104,000 mile. Every once in a while, maybe about once a yr. My engine check light come on. The code reader
reads read 2 codes 171,po171 The engine runs great though, so I clear the code
with the code reader then the engine check light  goes off It stay off for about another yr. The research I did points to the maf sensor. What is your opinion on this

maybe clean the maf with a non harsh cleaner ,just cuz it is always good to do .that 171 code says a lean mixture ,very common on that engine the defect is the design as quite often since some engineers must have been dumbed down the last few decades try a intake cleaner seafoam may do some cleaning,the stock maf is not quite matched to the pcm may need updated .wonder how much money wasted on this garb.

What do you mean by update?
