So I bought this on Saturday and took it home monday. The check engine light pop back on tuesday, used car dealership said they would take care of it which is why I didn't take it home till Monday night.
While driving for about 20 mins, aprox 5 minutes on the highway at 75 mph and 3000 rpms the temp gage jumped to hot then back to normal when I decelerated to 70. When I got off the highway the check engine light randomly turned back off.
What in the world??? Temp gage faulty or loose? Would that make the light flip on and off and the temp gage jump?
