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

first time i got a SES light, does this sound like the fuel pressure regulator or the fuel pump?

 

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.

time to go under the hood! plugs came today, is it safe to spray maf cleaner in the maf?

 

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.

thank you massey, i`ll just clear it with a friends tool, im not driving around alot since its been dumping gas

 

update- i gunned her *ss on a straight, and when it was throttling down SES went away and didnt come back, still going to change the rest of the plugs.
