QUESTION: While driving I lose power - the speed odometer stops working and then everything comes back up to power.  It does this off and on.  I had an error 21 and 14 - replaced the TPS and now have an error code 14.  Coolant sensor was replaced but still getting code 14.

Answer
Code 14 and 21,as you seen will be engine temp too high and tps sensor range also too high.The coolant system may be overheated,so try and change the thermostat or it may be the water pump is failing to circulate the coolant.One other thing is air in the system.
