my car is studdering

[Alastaplat]

hey guys.... I don't know what the hell is wrong with me car, but when I'm driving (from 2nd on) my car starts to like studder and go again kinda as if the clutch was slipping.... also too when I have it in neutral and rev the engine its not as loud as usual like it has a BIG loss of power, which is making me think that it isn't my clutch that is slipping, maybe something more serious.. can anyone help me please?? I'm lost without my car... I have a 92 240sx

it can be a number of things. vaccum leak, bad compression... who knows can you be more specifc? what RPM range does it do it from and ect.

after about 2000rpm it starts to you know, not decellerate, then accelerate right after again... but then I drove it to a shop the next day to get it looked at and it worked fine. but I didn't drive it long enough to know FOR SURE if it did it again...

I had the same problem, for me it was the injectors, and the o rings..

Also, make sure the vacuum line right above the fuel rail is good..

Take the 2 bolts off that round thing, and look at the rubber tube underneath it...

fuel pump or clogged or bad fuel filter maybe?
