I have a 1999 Tacoma 4 cyl. and it has been shutting down after it warms up to normal operating temp. It won't restart until it has cooled down a bit.
I have replaced just about everything related to the problem (fuel pump, spark plugs and wires, EGR valve, Pressure regulator, and also took apart the throttle body and cleaned that as well.
Any suggestions on what to do next?
