What specific ECU code?

Sure it's not coolant? There's a couple coolant hoses near that area. You could add some UV dye to your oil and check with a black light in a couple days.

Your oil pressure is in spec:

It is on the low side though...might want to check with a mechanical gauge at the sensor location. The fitting is 1/8" BSPT.

its not coolant its oily like ps or oil which probably relates to low oil presusure??wats around that area that has oil?

also code just flashes at 500 then disappears in a second

anybody with the tps?

from wat i got codes were
14

and

25


so 14 is that like plug wires an sparks?

and 25 thats a lot of stuff to check but i get horrible gas mileage so oxygen sensor?

also car is BONE STOCK so idk runnin lean

but fuel pressure would make sense since i have to try twice to start it

I would try the external igniter ground(search it) its cheap and easy. Not sure if it will do anything though.
Also check your TPS per TSRM.
I'm certain it has nothing to do with your spark plug wires.

BTW...Nice Ride:cool:
