I've been reading for a while, and worked through many issues, but I still have a few issues to deal with....I recently bought a 67 w108.....several months ( and $'s) later, it is on the road, but I found that the cold start solenoid was not wired up...connected it and starts much easier........then I noticed another wire hanging (idle problems, unless the idle is set high) ...then I noticed a temp sensor in the air intake plentum directly downstream from the air cleaner with nothing connected to either terminal. My question is what should the resistance of this sensor be cold and hot? And is one side grounded? Thanks
