so i turned my car on today and it ran fine i reved it it ran fine. than i fired it up again to see how my a/f gauge works and the car sputters and what now at low rpm but once i get to liek 2500 its fine. i noticed my temp gauge never went up. and senser is broken. but would this cause the car to barley start and run really rough.......... please help

I believe the PCM uses the engine temp as a factor for fueling or spark or both. Im not familiar with it 100%, but i know it would/should cause problems if the sensor was bad.

thank you.. it was the senser bought a new one put it in and a check engine light came on the senser had high voltage so i returned it and put another one in and it runs fine now...
