run the fault codes as misfire can be from injectors , low fuel pressure and ignition problems
all temp gauges will show a rise on stopping an engine as there is still residual heat in the block and heads with no water circulation and cooling
the fire from the exhaust indicates an exhaust valve is not closing properly so a compression test would be in order to check for valve problems or hydraulic follower problems
SOUND LIKE YOU HAVE A TEMPERATURE PROBLEM, HOOK UP SCANNER AND CHE THE TEMPERATURE ON THE ENGINE, DOES IT GET HOT QUICK, LIKE A CLOSE THERMOSTAT, IS IT LOW ON FLUID, DOES THE TEMPERATURE SENSOR READ OVER 200 WHEN WORM, DO YOU SEE THE TEMPERATURE GO BACK DOWN TO 15 OR LESS, ES TEMPERATURE GOES UP, LESS AND LESS GAS GOES INTO THE ENGINE IS INJECTOR SENS LESS AND LESS FUEL, THE TEMP SHOULD BE 180 TO 210 OVER THIS MEANS THE THERMOSTAT IS CLOSED OR THE WATER PUMP IS NOT CIRCULATING ANY COOLANT, BELOW 180 MEANS THE THERMOSTAT IS ALWAYS OPEN.
You may have a thermostat that is stuck in the open position not allowing the engine tom warm up fast enough to please the computer. Depending on which engine you have, locate the thermostat housing and replace the thermostat.
You could also be a little low on coolant. Take off the radiator cap when the engine is cold and check the level.
yes you need a new thermostat or there is low coolant. this will affect the mpg because your overheating and thats why its stalling. dont drive until you fix or you will blow your head gasket if it isnt blown already. change thermostate and check coolant.
To start with, you are talking about the temp gauge. The thermostat is in the engine. The coolant system could be low or have air pockets and still look full. First thing I would check is the cooling fan, then the coolant level.
