ok i have a 94 5spd SPED sentra, and for some reason, the car runs a lil funny and some point when u give gas, it fail emissions, and it said it can be one of the sensors on the car, i tried the o2 sensor first and nothing happend, im also gonna try the TPS to give it a try, does any one else know what i can be? they gave me a list, oh i also replaced the MAF sensor aswell, does any one know where the MAP sensor is located on this car?

 

The car doesn't have a "MAP" sensor per say, because of it having a MAF sensor. What do you mean by "runs a lil funny" .... need more specifics to give an educated guess.
