check the water temp sensor at front of engine. Its in the top water pipe.
Also you need to check the TPS(throttle position sensor)

looks at doing an ecu diagnostics check also to see if that comes up with anything.

sounds like temp sensor on top of rad, always gives problems.as connected to ecu, you need to clean the contacts ( yellow one ).
