Hi I've had FI light on and got lots of different opinions about it - mainly O2 sensor issue. Tried 3 different O2 sensor eliminators and an O2 sensor, none of which helped. Spoke to another mechanic today who advised me to take out the PCV before I brought it in...might save me $220. Only two wires he said... but after tracing a number of branches off the PCV wiring and eventually managing to unplug them all there were five seperate plugs coming off this thing. I've got two plugs I don't know what to do with... Please help!
