96' 240 having problems stuttering dying when driving.

when driving the car hesitates/jerks when you give it gas. if let off of the gas pedal, rpms drop the car dies. when i star the car i have to give it a little gas, if i let off the pedal the car dies. black smoke/carbon deposit coming out from the muffler (running rich).

changed out rotor/spark plugs/fuel filter. the fuel pump comes on i can hear it. some say its the distributor or fuel pump. been working on this for 2 weeks now and i really need my car. any help appreciated!

 

Check EGR, O2 sensor

 

changed the o2 sensor already, i'll check the egr val. anyone know where i can get the service manual for the 240? this would help me alot.

 

If Im correct u can order service manuals from a Nissan Dealer,other wise check ur throttle position sensor too,it might need readjustment .

 

www.phatg20.net has the service manual for the 96 S14. That's where I got the manual for my 95

 

depcwiz you da man! like the color on your 240. well......went out and drop 4 bones on a distributor.....if thats not the problem imma wack myself w/ a bat.

 

thanks! good luck with getting her running properly.

 

other than listed above, check timing, fuel filter, breaks in plug wires, idle adjust... off the top of my head

 

sounds like a bad EGR / o2 combo, had the same crap happen with my 95 9C1

 

check all your gas lines it could be your fuel pressure regulator or one of your injetors are clogged. check this things, i had an s13 do the same thing i replaced the f.p.r. and cleaned the fuil rail and injectors and it started up fine. good luck with it, let me know if you find the problem.

 

no luck folks. changed out the distributor, cleaned the egr val and injectors but nada. the car runs if you give it gas, but it stutters and backfires. i think the fuel pump is fine. any other suggestions?

 

Did u already check the throttle position sensor?

 

u should be able to pick up a haynes service manual at your local autoparts store, as far as your prob i agree with rivneo, it might be your throttle position sensor cuz u already looked over all the other possibilities that I could think of.

 

So tell me what car did u want in 1st place?
