    All of sudden, speed drops and car moves @ 10 MPH. We stop, and start again. Run fine. Happens almost once daily.

    Hi im Brett, My 2002 nissan sentra gxe has been having some issues starting after sitting overnight. it normally takes about 6 seconds to start but when it does start it studders like it is running on 2 cyl. then switches to 3 cyl. then to 4. but still studders like crazy. It shakes and the S.E.S. light blinks and stays on. I have gotten over 10 codes malfunctioning, i dont exactly remember them but like 3 fuel injectors were failing, mass airflow sensor failed, alot more lol. But it studders when it is being driven and likes it when you push the pedal to the floor. It tries to stall when at idle if it has been driving.

    already had this replaced 12,500 miles ago - DCH Freehold Nissan refusing to stand behind the replacement beacuse they say they onky warranty for 12,000 miles! They want another $500. to repair! Outrageous, last Nissan I will buy and this was our third.

  • I have a 2006 nissian sentra i also had a problem with the check engine light I took it to the shop four times before they found the problem was due to throttle body. the price was quite high 625.26 so far it is running good. I only have 58k miles on it.if it happen again, I'am going to trade it on a honda Accord!

    I've now had to replace the throttle chamber/throttle position sensor twice since I bought the car in 2006.

    Service engine soon light comes on and the car goes into "Limp Home Mode" A quick temp fix that I did about 36 times at least, was to shut oof car remove key put key back in and start. Will look into a new Throttle Body (Electronic Throttle Unit?)
