Bought the truck the other day. when warm it started up perfectly. After sitting overnight and trying to start the engine cold it sputtered and choked and the only way i could start it was to give it extra gas with the gas pedal. Even then i had to keep revving it up and it took almost 2 minutes to achieve a steady idle. Some suggestions were to put in a new gas filter and fuel injector cleaner. Does anyone have any idea what could be wrong.

 

Tons of possibilities. One I would say is the coolant sensor.

There are 2. One 1 wire for the gauge. One 2 wire for the computer, replace that one.

 

i've got a bad iac that does this in the winter time.
you can test the temp sensor with a volt meter. specs are in the fsm for temp and resistance curve.
