Hard engine starting Rich or lean air/fuel ratio Reduced fuel economy Hesitation on acceleration i was told the coolant temperature sensor can cause that, because im having all those problems, i pulled codes, im getting lean in bank one and bank two, so i thinking this might be the problem
If you have a voltometer, get a resistance reading across it. It should have a huge resistance (something like 50k) when cold, but at operating temp it should be 2-3500 ohms or so. If that's good, then check the voltage across the electrical connector... 4.5-5V or so.
