its a vacumn hose issue,,,need to look for a cracked hose at the rear of the motor,,down about half way .
If the "check engine" light is on, use a code scanner to find out what's wrong. You can borrow, rent or buy a code scanner from most auto parts retailers. Sometimes they'll even show you how to connect it and how to read the results.
check all the Fuses and fuse links (Altnator to Fuse box to battery)
If the plugs, plug wires, are good then suspect a vacuum leak somewhere.
its most likely your idle control sensor. if you replace it the truck should run fine.
Check your fuel off / on swich. Pull the to screws out and check the filters.
more than likely u need some fuel injecter cleaner that is what was wrong with mine
Ask this question again specifying what the car is.
vacuum leak.
check your idle controle moter. it is probably crudded up or not wotking.
Wrong page.
the only reason a car will run rough or not start after refueling is either the wrong type of fuel has been put in[i.e diesel into a petrol or visa versa]or the fuel put in is contaminated.
I would check the temperature sensor. Sounds like the sensor is telling the computer wrong information and the the fuel mixture is being affected.
