Could be a defective fuel cap, or you just need to take the cap off and put it back on.

Starts and idles, no accelerator response.


Your Denali has Throttle Actuator Control (TAC) System - Electronic throttle control ! Are there any messages on the driver information center ? Reduced engine power ?
Reduced Engine Power Mode When the PCM detects a condition with the TAC system the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Acceleration limiting--The control module will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.


?€¢
Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.


?€¢
Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.


?€¢
Forced idle mode--The control module will perform the following actions:


-
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.


-
Ignore accelerator pedal input.


?€¢
Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.


You need to have it checked for DTC'S - diagnostic trouble codes , probably a accelerator pedal position (APP) sensor or TPS - throttle position sensor !

2003 mountaineer V8 Temp gauge jumps to hot not over heating. Replaced thermostat, no change


The Engine Temp. sensor is bad. it is under the intake manifold. if there is a miss also check under the coils over the spark plugs. If there is Coolant in the spark plug holes .then the intake gasket is leaking. The intake manifold needs to come off to change the coolant sensor. When off look for corrosion on the cylinder head at the coolant port. If there is corrsion then the cylinder head must be replaced.

Why does it say check fuel cap


Your fuel system pressure sensor is detecting a vacuum leak. Sometimes it is the cap, sometimes there is a leak in the vapour recovery system. So check your cap. It can reduce your fuel economy. good luck
