SOURCE: Oil running out my tail pipe
Excess engine oil can only enter combustion chamber from four areas, (1) the intake manifold [pcv system failure], (2) Valve stem seals worn out [pluged oil return holes in heads causing oil to get sucked past worn seals] (3) Worn/varnished up/broken piston rings,(4) Highly unlikely but a hole in piston. Since you only show excess oil on left rear, suspect #2 or #3 although usually more than one set of rings will wear out or (gumm up).Check compression with all plugs out, ignition & fuel disabled, i believe 120 to 150 psi is good, if ok , check #2. If this has the older efi intake, its rare, but also could have a failed intake gasket for that cylinder and be sucking oil from underneath.Hope this helps!

The fuel pressure regulator does not seem to be working. It should hold fuel pressure in the injector lines. Your fuel pressure may also be to low.

Bad injectors causing the vehicle to run poorly can cause other damages to sensors etc. Buy a code reader and check the codes.

E.C.M control injector pulsation, with key on check for voltage at injector harness, then reverse test light at battery and check for ground at the other wire at injector harness, crank engine ground should have pulsation if none bad E.C.M,good luck,hope this was very helpful.
