Please help!**
I own a 2002 s type with 2 codes I cannot Figure out, a P0300 and P0442. Ive been trying to figure it out for 5 months now. When it sits longer then 10 minutes it is harder to start ( takes like 5 seconds to start), and when it starts the tach Flutters for a couple seconds and eventually smooths out. Sometimes some smoke comes out of the tailpipe ( driver side). It leaks a small amount of antifreeze. The fuel pressure goes from 57 (ish) psi while running, and drops to 15 when the car shuts off. I also see some type of smoke coming from behind the engine in the driver side. Ive taken off the coil packs and have also noticed oil on the boots. It makes me believe I have a bad intake and valve cover gasket. I’ve already changed the fuel pressure regulator and some kind of valve for the evap system. If you want any more information please ask, I’m not the best with these. ANY help is appreciated!

 

Fuel pressure dropping so fast suggests a problem with the fuel system, be it a leaky injector (#1 suspect for me), back near / at the pump or whatever.
