84-GSLSE

This is really weird. When i am driveing my car and i push the clutch in to change gears, and i let the tach drop down to idle(you know if you are useing the brakes and dont want to heal/toe)it will go all the way to the bottom. almost to the point where i can feal the engine want to stall out. but it always recovers and pops up to the normal 700 rpms. unless i use the ac, then it stalls. But this still is not the weirdest thing that has hapened. if i go and park the car and sit in my seat with the clutch in and no gas the tach will move. it will bounce up and down a hundred rpms or so. also i noticed that the oil pressure drops below zero, then it will shoot up a few psi then slowly drop back to zero, then shoot up agen. i dont really notice a corraspondence with the tach. I first noticed this happening a few days ago when i was comeing back from the drag strip(no i diddnt run). I would say it is about a 35-40 mile ride. I dont know if that has anything to do with it. Oh by the way my car is a 84 GSL-SE.

If any of you guys have had any problems with this kind of stuff before please let me know. it does not really afect my driveing that much, it is just annoying.

I've had mine bounce on me..

but the weirdest thing that it has done to me. Is a while back, when I popped it into neutral to coast to a stop, the rpms stayed at about 2000 rpms, until I came to a complete stop, when it then wen't down to 700. This happened for quite a while, too. It doesn't anymore, I don't know why.

I have the same problem with the idle , but only when coming out of reverse! The rev's will shoot down to maybe 300-400 then will recover and go up the normal the 700. No idea whats causing it. Also have the same prob with the bouncing idle.

Any fixes would be appreciated ! BTW '87 rx-7 N/A

NOW THE TACH STAYS IN THE RIGHT PLACE WITH MINIMAL MOVEMENT BUT THE FU@KING OIL PRESSURE GAGE JUST SITS AT FAR LEFT OF THE DIAL. The smae place where it sits when the car is off. If i nudge the engine a grand or so it will bounce back up to the right spot. WTF!!!!!!!!!!!!! Cant anyone here help me?
