hey guys i just bought a 93 toyota pick up v6 3.0L. and i love it, but i have two problems that are really pissing me off. i didnt find this problem until after i bought the truck and drove it for a while but if i hit certian bumps or dips my cd player turns off and on, my cruise control shuts off(as if i hit the brakes, not all the way off) and since my sirus radio is plugged into my cig lighter it turns off too. and if the bump is a good one i think it kills the engine and messes with the speedometer. i dont know if it is a bad ground or what? another prob is my truck never use to overheat but now it loves to if i go over 65. i replaced the thermy and i really dont think its the radiator cap. if i could get some help with these two problems it would really help enjoy my truck to the fullest. any ideas would be a great help!
