Okay, I just bought a 1992 240SX today. It's auto trans, appears to have dual cams. There's a few things here and there wrong with it, so any input on these things would be a great help. I'll put my guess in the brackets next to each problem:
Noisy exhaust (no muffler mod), faint rotten egg smell (cat convert ?)
Transmission sometimes won't go into gear from reverse to drive easily. Basically, after backing out, when you go into drive, it stays in neutral for a bit before going forward. (no clue)
Idles very rough. Sometimes will dip down to 500 rpm.
BIGGEST MYSTERY TO ME: The car rear end tends to sway back and forth. Real floaty. It's almost like it's shakin' it's *** when you drive. I just put a brand new set of tires on it, so that's not the problem. Any clues on this one would help greatly.
This is my first post and my first 240SX. Eventually, this thing is going to get the Silvia swap out. The other stats on everthing is:160K on the car and the trans. The engine was recently rebuilt (not dealer) and has 5K on it. There's a few crap mods done by the previous owner (high school kid) that I'm going to have to undo. Small stuff - like foglights mounted incorrectly (wired straight to the battery) mainly dealing with accessories.
Hope you guys know some of this. Thanks.

1 most likely
2 yes if it wasent gutted when the stright pipe mod was done.
3 could be a bad shifter bushing in the linkage. check your trans fluid level as well.
4 this could be a wide range of things. AIV,IACD, there are numours posts on this subject alone in here and primarily in 240 technical. do a search on rough idle you should get several results.
5 suspension bushings, bad struts in the rear.
Okay, well I just went through the car's paperwork today. Looks like the transmisson was swapped out with a rebuilt in 99. You think it would go out again this quickly ? Probably has about 30K on it.
As for the rear sway problem - is it more likely bushings or struts ? I planned to replace the struts anyway, so I'm hoping that will fix it.
The rough idle problem just has so many variables. I'm going to take it to the local garage and see what they can figure out.

Okay, I'll get the place that swaped out the original transmission to take a look at it. What does that sort of thing usually cost (replacing bushings) ?
Also, if I just totally replace all the struts, will that cover the bushing problem as well (do the bushings come with them - I'm not sure - I'm used to dealing with plain ol' shocks).
Thanks for all the advice so far.

Yeah, I plan to give it a once over tomorrow when I have more time. Also going to let the local garage here do a total inspection of the car and give me the "list" of stuff I need to get fixed.
Okay, well found out the problem. Turns out it was REALLY bad. The frame was bent on the car and the rear axle was cracked. Turns out the lady who sold it to me, didn't quite give the whole story. So, I ditched the 92 fastback and got me a 91 instead (non-hatch). It runs a LOT better and it's a manual versus auto. There's only two little things it needs which I'm going to cover in another thread. Thanks for the help on this though
Well apparently the whole frame of the car was slanted. You could see where the screw holes didn't line up under the hood where the body panel attaches. It was pretty bad, I can't believe I didn't notice it. On top of that, the rear axle itself was cracked. The person that sold it to me said it was just in a "slight" bump from going into a ditch. That car wasn't even fit to be on the road.
