Engine Performance problem
1995 Ford Taurus 6 cyl Front Wheel Drive Automatic 130000 miles
My Taurus has been acting up. Poor idle at various times then smooths out, misses and bogs down on acceleration and backfires cold through the carb then goes away not all the time on either and intermittent check engine light (comes and goes) no codes.
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?
