When the car is cold I can start the car fine without any problem, but once the car warms up and I shut off the the car and try to start it again cannot start would have to wait for a while until is cold again. After the car has electrical problem and shorted the gauge and also the driver side multiplex control unit is burn out and it start doing this on the gauge there is the the VVT4 and check engine light that goes on. Also, the code is ( coolant temperature sensor circuit hig ) and the others one is idle air control valve circuit malfunction. Please help me. Thanks

It may be the multiplex unit. Scan for codes and check fuel pressure, but things that are already messed up must be fixed first.

Sounds like the coolant temperature sensor could possibly be faulty.

My car will start but when I take my foot off the gas it shuts off. What can cause this?

There could be a clog in the fuel filter if applicable. The throttle position sensor may be bad. Before you look into these items get the fuel pressure checked. Advance Auto and Auto Zone both loan out test kits for this.

I replaced the throttle position sensor and now the truck the cl idles fine, but the service engine light is on. I had Auto Zone to test it and it gave PO122 Code. What can cause this after I replaced the sensor?
