92 240sx Acceleration problem.

[Florida240sex]

I bought my car about a year ago, when i first test drove it it ran great, it was pretty peppy and put a smile on a 16 year old's face. Anyway it sat for about 6 - 8 months while i was gathering the cash for registration/insurance, once i finally had enough and got it on the road it was much slower than it was before. What's happening is that when i accelerate it kinda bogs down, when i rev it in neutral it's fine, if im driving on grass or loose dirt it also seems much better, it seems to only be a problem when it's under load. I did a burnout with it when i first got it just for S's & G's and it suprised me, so after i got it on the road and started noticing this problem i decided to rev it up and pop the clutch, and upon doing this the tires let out a quick chirp and the engine bogged down almost to a stall. Also when i first got the car i took it up to the spped limiter (115), and now i can carely get it to 100. Don't get the wrong idea im not a crazy jackass driver, i don't haul ass in heavy traffic or in mild traffic for that matter, any time i ever go fast is on a backroad with no houses or poeple that could potentialy be hurt and iv'e only done this a few times just to compare it to the way it was when i first bought it. Now iv'e already replaced the fuel filter aswell as the cts (coolant temp sensor) and it's not a clutch problem, so if anybody can give me advice on what could possibly be causing this i would really appretiate it, i want to do a ka-t build with it but not untill i solve this problem.

I'm going through some similar problems but with a more refined set of symptoms.

Check (in this order)
A) spark plugs and wires,
B) distributor cap and rotor,
C) Fuel pump/filter

I would do what dustin_s said, cap, plugs, wires, rotor, and air filter. You said you replaced the fuel filter. If it still does it after that then get the fuel pressure checked, cuz it sounds like a bad pump. I had similar problems with my escort and the tune up fixed that, but usually the symptoms indicate bad pump. Does it stay relatively the same with the bogging down at all rpm's, or does it get worse when you get to higher rpm's?
