Unhappy engine problem (Sentra XE 2001)

My car is running weird, when you want to accelerate, it's like the car doest shift..instead it's slowing down and you must release the pedal if you dont want to stay in place with the engine reving for nothing....it's very hard to accelerate, ...i though the problem would be the O2 sensor (because the check engine was lighted up) but I just replaced it, same thing (but the check engine light is now off)


plz help

Maxtin,

Check the thread of 2001 sentra has no power--

It sounds like you have the same problem that I had. If so, It will be the fuel screen and the injectors. To verify this, you can squeeze the return line on the fuel supply. Then rev the engine to see if you have better performance.

If it is also the injectors, I found a place where you can get all of them for $100 dollar plus 30 for shipping.

Hope this helps.

take the car to autozone and get the code checked first. Then come back here and tell me the code and I can tell you EXACTLY what it means from the factory service manual

billbill, I appreciate your suggestion, but we need to first see what codes it's throwing before determining something like that. 9 times out of 10 the fuel screen isn't the problem.
