I get p1167 and p0171 codes now, before this I was getting p0160 which disappeared. I do have misfire codes as well. Is it 02 sensor or something else. I did have a vacuum test done, replaced the fuel filter and air filter, cleaned the MAF and added fuel injector cleaner twice. If it is the 02 sensor, which one and where is it located.
Also when I removed the plenum to replace the spark plugs and accidently pulled out the wires to a electrical connector on top, I pushed them back in but I think one wire might not be in. I have no clue what these wires go to, does anyone have an electrical specs for the engine compartment?
