Hi again.... Engine hesitates on low RPM's. New EGR valve and EGR solnoid. (Not new EGR sensor) No code. Runs much better with vacuumline to EGR valve off. But then the CEL light comes on of course and uses much fuel. New wires and cap and rotor and plugs and AIC valve and canister purge valve. Timing checks OK several times. I can't really figure out what is doing this. Have read about a PFE or DPFE transducer which maybe can have anything to do with this. Where is that located in the engine? Maybe a bad PCM or ECU or what it is called? Can anyone please help?? Regards, Tor....
