1995 GMC Jimmy SL 4.3L Excessive Emissions, Hesitation, Misfire, MIL Lamp on
Rough running cold, replaced oxygen sensors, coolant sensors, ecm, and tune up parts...no change. Noticed that temperature voltage from scanner would start at about 3 volts(@[...] celsuis) would drop as vehicle warmed and when it reached 1 volt would jump back...
