Newbie with fc problems!!

Hello!! This is my first time posting on this web..
Anyways.. I own a 2dn gen gtus that has few problems..

1st my oil pressure guage doesn't work. I tuke out the instrument cluster and checked if it was disconected, but I looked and everything look fine to me.
so I believe I have to move to the engine, but I dont know where to check for the oil pressure. so plz rotary guys please help..

and another thing is that when the car goes over 60 mhp it starts to become unstable..

Check the connection at the oil sender unit. It is located next to the spark plugs. Its about the size of a golf ball. Has a single wire running from it. It is bolted to the engine block.

Your second ? I would guess a tire balance.

Welcome to the club!!!!!!!

tire balance would be a vibration at 60mph, unstable would be alignment or something loose. check lugnuts and sway bars then go get an alignment.

like free said, your wire came off the oil sending unit. female blade style clip on the wire goes on the male blade of the unit. its located below where the oil fill is.

O.K. I checked the connections of the oil sender unit, and it was cover in grease, so I cleaned it disconnected it, and connected it again, but still didn't work, so my guess is that I might need a new unit, or check the little wire that connects to it and see whats up.. or maybe I don't have oil pressure but would be impossible because the car runs fine!

NOT TRUE!! The car can have low oil pressure and still run great! It just won't last as long. You should check your oil pressure with a mech guage just to be safe. You could also try replacing the oil pressure sensor with a new one. Inspect the electrical line.

You could also install a custom guage as well.
If this is all above you take it to your dealer or a shop you trust!!!

Out of round tire (separated belt), tire out of balance or severely damaged inner or outer tie-rod ends.

But an alignment will NOT cure your instability.

O.K. I'll check the oil pressure sensor and the electrical wire and if I can't fix it I'll take it to the shop. BY being unstable(instability) is that the car pulls side to side at high speeds. mostly to the left.. just wandering wheres the oil sensor.. Thanks guys for your help..
