Default Overheating, Shuddering, and oil pressure!!!!

Hi, I have a 95' sse with 113k. Man.. this thing is acting funny. I cant firgure out the problem either. I had the coolant fans and relays replaced about 3 months ago and the dealer told me I have a oil leak around the seal. I think that explain the oil pressure jumping around but Theres no holes in the oil pan but it leaks a small puddle when it sits over nite. I know i gotta fix that but it doesnt it explain the jerking of the car at low rpm'*. When im in Over Drive around 28-40 mph @ 1500-2000 rpms the car feels like im going over small bumps in the road. Also the engine temp. is going crazy sometimes it reads at 200 but then some days to goes all the way to redline. My car shifts fine and I have read the other post about the plugs and wires or a tranny cooler ( Cant afford that ) I just need some guidance before i spend my college money.

First things first, when was the last time you had a tune up [plugs, wires, o2 sensor, fuel filter, etc..]. Your oil leak may be due to excess pressure buildup, due to a mal-functioning PCV Valve. You may want to make sure the PCV Valve is operating properly. And that you have sufficient fuel pressure.

Yes, littlehoov sounds like he speaks from experience. They are a dollar or two.. not expensive. After that, do a full tune up:

plugs
wires
o2 sensor [unless verified under 12 mo old]
fuel filter

You're gauge issue sounds familiar. I believe you may have cluster issues if your two/three gauges on the far right seem to have elpileptic seizures.
