0174- fuel trim bank two condition
0171- fuel trim bank one condition

I pick up system too lean bank 1 and 2. Common causes are FPR stuck open, clogged fuel filter, low fuel pressure, bad or incorrect MAF/MAP reading.

Yea it is safe to use MAF cleaner on the MAF sensor. I would take it off the engine first, if you can.

okay results-

changed the pcv valve, and noticed the two inch hose between the pcv and intake cracked and had a hole in it, the fat end of the old pcv had some oil on it. looked at other hoses didnt notice cracks.

put 4 new plugs on the driver side with msd wires, car seems peppyer but the rear wheels i can feel a hop/skip when burning out or taking a turn on the gas. maybe i`ll just go back to a basic rubber mount, thats whats causing it though? right?

would the light come off by itself if the problem is fixed or would i have to clear it with a scan tool?

It will eventually shut off by itself but it could take a while depending on driving times and habbits. It is best to turn the light off with a scan tool and if it stays off your problem is solved if it comes back on then you know you didnt fix it.
