help me get rid of my code
Hey everyone! I just bought a 2000 L 2 weeks ago and the check engine light came on when i got home that day, so i called the guy immediately and he said its never came on the 6 years that hes had it. ( really nice guy) Said his wife put 87 in it about a week before i got it and he didnt drive it that week due to her being pregnant and trips back and forth to the e.r. So we have done some talking about the code ( p0171) he says its the gas and it will go away after i change the fuel filter. Should i try that or is that not going to fix it? He also had a JLP Thunder Tube and JLP ram air box on it that he took off, and put the stock tube and a LFP 12" deluxe powerstack c.a.i on it. This is what a google search told me.
"This causes the maf voltage to read lower, and conversly less fuel is mixed in, then the o2 sensors read the lean condition, and when they reach a certain threashold of adding more and more fuel you get the lean codes."
Also says i need to retune my truck or put the stock maf sensor back on. i can write out the rest of the stuff done to my truck if i need to, any help i would appreciate!
