my 240sx is sick
ok this just happened out of the blue, I drove the car one night to goto gf house and it ran fine. The next morning, I had a hard time starting it and when I did it had a rough idle and ran really rich.
What I've done so far is cleaned out the spark plugs, checked to see if the wires were bad, checked vacuum leaks and changed O2 sensor. Im stuck. the only thing i can think of is checking the injectors resistance and changing the fuel filter, which i will do tomorrow when there is light and the stores are open.
Any input as to why this would just happen out of the blue? Any input would be appreciated.
I should also add that when i press the throttle all the way down the engine bogs and revs really slow or not at all sometimes but if i go half way it will rev up

Re: my 240sx is sick
You said if you give it half throttle it'll rev up but not on full throttle?
Have you checked your TPS? Your TPS may have shit out. It should be at ~0.45mV or V (I forget the setting on the multimeter).

Get a FSM (factory service manual) from offline. If you have a SR download the english S14 SR one as it will be basically the same for trouble shooting crap like this.
