I need some help friends I'm at witts end... I have a 2006 charger R/T 5.7 with 140 k ... It has new plugs new water pump lower hose and new mass air flow sensor .... The car started giving trouble by stalling and giving me a code number one cylinder misfire .. I replaced the 16 plugs worked great ..then I would start to floor it at 25mph it would take a dump at 4000rpm in first gear only ... No codes ... Now it's starting a new thing the oil pressure is dropping after I run it a little hard it goes to 0 but the car is idling just fine NO noise ..it's full of oil and has same type of oil since new Same weight and brand ..., amsoil 0w-20.... With no problems .. When it hits 0 I shut it down and restart pressure jumps back to 35-40 at idle ... I drive a little hard it drops and keeps dropping ... It currently has 1/2 tank of pure gas but is giving me same crap on the 10% ethanol crap ... Any suggestions please help ...
