I recently bought a 92 sc300 and it starts but runs super rich and floods the cylinders, first I thought it would’ve been the ecu because I read that that’s the major problem with these cars but I got it rebuilt and the is still the same I did a compression test and it builds up slow and caps at 140-147psi except cylinder 3 which is 90psi
another issue is when I crank the car to see if I fixed the problem fuel leaks into the oil
I’m wondering if I should change the fuel rail and injectors with my gs300. Just looking for advice here can’t afford to get it towed to a shop right now

 

Sounds like maybe you have an injector dumping fuel. First guess anyway.

 

Yep, sounds like a stuck injector. Check those first.
