I have changed the plugs, wires, cap, rotor, coil and fuel filter. Checked and cleaned EGR valve, ECT, ACT, IAC, MAF, PTKFE and fuel pressure regulator. I also checked Evap and emission system, intake manifold and vac hoses and brake booster for vacuum leaks and obstructions nothing noticeable.I also put a spark window on the coil (nothing noticeable), vaccuum gauge(steady at hot idle 15-20) and checked fuel pressure(steady) drops to 32psi (fpr disconnected) at injectors normally 39 psi. What do you think?
have the same problem?
