My engine is running either too ?
i have changed the spark plugs and changed the ignition coils to see if that will work( at first it was saying that i had a miss fire) now they are saying it might be the oxeygen sensor or the mass air flow sensor. it is a 2001 chevrolet prizm. how can i find out which sensor it is so that i don't waste money it is almost 400 to get all 3 sensors ( there are two oxygen sensors to change)

i already had the test run its saying that it is running lean or rich
if i spent the money and got the 100 dollar diagnostic would this be more specific as to what needs fixed2001 chevy prizm engine light?
I told you already in your last post.
You need to make a shop visit.
Lean/rich codes from O2s does not mean the O2's are bad. They are doing EXACTLY what they are supposed to do!
Spending $400 got nothing done, so get it done right!
