Hey guys I have a question for you. As you can see, I have a 1993 Chrysler Lebaron LE with that 3.0 V6 SOHC. When I bought it, it had a case of old people abuse(not run hard but neglected). I slowly replaced parts (Radiator, water pump, tensioner, all the hoses and belts, engine coolant temp sensor, thermostat). There is one problem left. My engine temp is always all over the place. I start my car up and the temp gets past the 2/3 mark and cools down really quickly and does that over and over again. at first I thought it was becasue it was a cheap thermostat, I went to Chrysler Center and payed $23 for one. It still does it. Please help.
