another problem dangittttttt

[blk240s14]

well i was driving the car tonight and i took it up to about 4k and then let off.. as soon as i tried to give it a little bit of gas it wouldnt even go past 2500rpm.. luckly i was able to pull over and got it towed.. when i try to give it gas it just sputters really bad.. the car will start and idle ok but as soon as it gets close to 2500rpm it just starts sputtering and wont go past.. well any ideas?? thanks

If we knew what kind of car it is we might be able to help.

could be lots of things. Limp modefuel problemtiming problemMAF

Those are just off the top of my head, with out knowing what kind of car it is.

EDIT: Just noticed you screen name, you probably drive a black s14? do you have a KA or is it swapped? If it is swapped, what motor?

my bad man.. its a 1996 240sx got the sr20det s14 motor in it.. it was running for a few weeks but it was sputtering really bad at 5500rpm i had another post on that prob.. and this one is just from tonight ahhh sucks ***!... any suggestions?

I had an issue with my KA not wanting to rev past 5.6k. Turned out that the top timing chain had one of the cams off a tooth or 2. Are you getting good fuel pressure?Is the timing set right?Is the MAF functioning properly?have you comp tested the motor?is it throwing any codes?

I would go back and double check the timing, make sure nothing has loosened itself and adjusted the timing or that the chain hasn't jumped a tooth.

That is all I can think of off the top of my head. I don't really have any experience with the SR's. Might have better luck getting this thread moved to either the SR or or online mech sections though.

Good Luck

Email a mod, and ask to have it moved.

ECU sounds to be in limp mode.

pull the maf out of the equ and see if the conditions change. if they stay the same it is the maf.

decent vac leak will cause this

leaky injectors.

bad ground....

you need to really get into all the specs of the car, what conditions you are experiencing and lay them out. otherwise it is impossible to diagnose anything.

anti-acids dont do you no good for a fever and anti-biotics are no help for a bad rash.
