Engine Performance problem
1993 Mercury Villager 6 cyl Front Wheel Drive Automatic 204000 miles
It starts and idles great. On acceleration it acts like it is starving for fuel sometimes back firing in the intake.
Fuel pressure and pump delivery checks out good. New cap, rotor, plugs, wires. It's set a code 33 OX sensor cicuit and 34 knock sensor circuit. Installed OX sensor, no difference, Knock sensor hard to get to. Any other suggestion. Checked timing it is advancing as it supposed to. If you pump the pedal as you start to accel it will wind up with power than flatten out unless you back off the pedal. Sometimes it will have power intermittenly. Thanks John
have the same problem?
