Buick Repair Questions? Ask a Mechanic for Answers ASAP
You are gonna love this, but I am trying to feed a leaner signal with the Innovate LC-1 wideband sensor, but had to hook up the heater section of the old sensor dangling in the open in the engine component to keep the P0135 signal away. Running HHO trying to get better mileage. Its resistance seems to be one half the normal amount after a few months. (got wet?) I haven't checked the fuse yet but just in case, any possibility the PCM circuit got damaged? If so, would any similar GM model V6 same vintage PCM work without reprogramming?
