What could the problem be?

[Canuckrz]

did you pull the codes? Wouldn't I need a programmer to do that?

is there any smoke? if there is, what color? Yeah theres smoke, its your typical grey smoke as far as I can tell.

is there any oil under the car? If it was it wouldn't be major, I'll put some newspapers under it tonight to check.

did you use premium gas? Not sure what the buddy who I bought it off of was using, likely regular.

what's the milage on your supra? how long have you had it? what work have you done to it so far? 147k km, a day, nothing yet but it looks like this problem is going to open a can of worms.

when you step on the gas does your oil pressure increase? Yes

is there oil in your intercooler? How do I check that?

is there coolant in your overflow? Yes.

Thanks for the help thusfar.
