240sx from hell =[ HELP!!

[bdeming]

ok so.. ive gotta 92 240 with the ka24de.. which idles horribly, shakes the whole car, it misfires from idle untill 3000rpms and has no power.. ive searched through posts and i cant find anything to help me.. ive gotten a new distributor cap/rotor, new plugs, new fuel filter, injector cleaner, the wires seems good. im not sure where to go next. the problem seems to be the cylinder closest to the firewall (cyl. 4?) not sure im a honda guy. im guessing maybe an injector? what else could it be.. the head gasket is fine

also, ive got a problem with my lights, in the day time they will come up fine, however at night they wont come up EVER.. and i end up cranking them up by hand, any idea? ive got a few more problems with the car but these are the ones i need to fix.. i feel like im driving the car from the movie "christine" haha, it just seems to do what ever it wants

It seems like the injectors in these cars fail a lot. Could be an injector. Look for cracked or died or hoses.

As far as yuor lighting, try replacing the combination light (ie your turn signal switch). I've had 2 bad switches... Those fail a lot too.

start your car and pull one injector plug at a time until you find the one that is causing your issue. the one that doesn't change the running condition of your car is the one at fault.
