    ok on the adjustible suspention... there is a button on the far right well a switch of the center concle right next to the miror defrost and the head light wahser switch... there are three spots "S"(soft) "N"(normal) "F"(firm) when you want ether one you just move the switch to the desired one alowing the suspention to switch over and that one letter has a green light behind it that lets you know thats the one you are on why the others are supose to be off. it will work fine for a min when i turn the car on becuase if you move it you can hear the suspention changing, then it the other two lights start flashing showing there is somthing not working correctly, and then you will also here the suspention just shut off cause you hear the little motor or what ever just realse it

For the fuel gauge, get a new fuel sending unit and replace the existing one, since it appears to have died (not all that uncommon). For the oil pressure, my 90 300ZX TT had a problem there too, and it was the oil pressure sending unit. Both parts are available at a wide variety of places, and neither is terribly expensive.

As for the suspension, I'm not sure what you mean by the "other lights" flashing - which other lights? Is the car stuck in Touring or Sport mode on the shocks, or does it change when it wants to, or does it not change at all?

1.2 manual reverse gear problum

Manual transmission does not change gears with transmission oil. If yours is the AMT type, get it scanned for error codes.If the problem is in shifting into R, get your clutch cable adjusted. Your clutch plate may have also worn out. If shifting is OK but the car just does not move, the gear linkage/cable may need adjustment. If all else is OK, the reverse gear in the transmission may have been damaged.

You have more problums than that,

Does it also have problums shifting? I.E. staying in the low gears?
