These are the codes I just read from a 2001 Tacoma V6 2WD. Changed plugs and wires (not packs) last night and of cource this is when it started running worse than when I began. I used NGK dual tip plugs like the factory had put in it.
The CEL was on previously but I'm not sure what code it was. The truck has been going down hill since late August when I bought it with 134,000 miles on it.
The truck has not had regular maintenance ever, original everything! Oil change and tire related stuff would be my guess at the only work done to it. Original belts hoses and timing/water pump....everything.
When I pulled the plugs on the drivers side they looked different than the passenger side, darker and looks like oil deposits. I originally bought single tip NGK plugs so after I read that's a nono I then bought the dual tip NGK's. With the new plugs I ran it for maybe a half hour last night and when I swapped them for the dual tips today the same side was darker and seems to have oil deposits!
I'm not well versed working on automobiles and usually pay for all my service but times are harder now and I'm trying to save money. The local garage I go to wanted 2.6 hours and $210 just labor costs to change my plugs so I said no way.
Please help me!
