Hi guys I bought a 300zx tt and on the way back to my place it was jerking on idle and it wasn't going over 2500rpm. It got to the point where we had to push the gas pedal while turning the ignition to get it to start up. I checked the ECU and got error code 53 which is the exhaust gas sensor unit. The car is also leaking oil and only has one turbo currently. It makes a air sucking sound when driving somewhat like a vacuum sucking air but I guess that's the turbos. What should I take a look at first? BTW the previous car owner died 2 years ago and his dad sold me it so it barely has been driven for 2 years.
I need as much help as I can get. Apparently the hose is also wired from the plenum to the turbo and it's also bent. Not sure why,
