Alright its like this;
Its a 94 T/A M6 with 110k, when the engine is cold it runs great, but when it gets hot it starts running like crap and the oil pressure drops really low. Sometimes, when its hot, and i am trying to take off from a dead stop it feels like it wants to stall!! What could this be ??? Any help would be greatly appreciated, thanx everyone.

how low is your oil pressure?

Yes please post what your pressure is. Check to see if the pickup fell off. You can hear a rattling on the bottom of the pan if that is the case. That is a fairly unusual but common problem.

Oil pressure and your stumbling problem are not related. Might be time for a new opti and plugs and wires.

My oil pressure is at or above 40 when it's cold, once it gets warmed up it goes down to about 20 or just above. It's been like that ever since i've gotten it.

Mine starts out at about 50 and then drops all the way to 10-15psi if im lucky. I use Valvoline durablend 10w-30. The car builds pressure and holds it normally and drives perfect. I'm changing the sending unit to see if that helps any.

If its the opti, What are other symptoms if it being bad?? Ohh yeah, I use only synthetic oil, the oil pressure sending unit is also new, and i just got done putting new plugs and wires on . Come on guys i need more help figuring this annoying a$$ problem. Thanx again for all the advice keep it coming..

when your car is warm 20 psi with the stock pump is normal

dont worry about it

Its not just that, when the car is warm (around 220 or so) the oil pressure drops alot and when i am trying to take off from a dead stop it feels like it wants to stall or something. It won't stall though if i give it a good amount of gas just to get it moving. The car feels horrible when its hot!!!! Some people said that it may be my EGR valve or sensor one of those and some said, because it is only like this when its warm, its not my opti. Is this true??? Thanx again for all help, and keep it coming please!!

Have you checked for a bad o2 sensor? Also, does it run rich when it starts to run bad?
