sputter problem
 

ok my friend has an 02 sentra and when she starts the car it sputters and then she has to push the gas to get it started i noticed therer are two cables on the throttle body and the one closest to the throttle body looks loose also it doesnt happen all the time also the check engine light will go on and off from time to time. is there a way to check the code yourself with out the computer im not sure like i have a dodge and u do the key dance where u tuurn it on/off 3 times then keep it on not starting the car and the cel will flash a set of numbers which will give u the code
thanx
