Below is a list of things to work through. Check or replace these items: -Check timing -Check throttle position sensor switch settings (will either be a tandem set above trottle body or a single switch underneath) -Temp Sensor II (I'd just replace this if it has over 100K miles, these go out of spec frequently) -O2 Sensor (sometimes a factory wire O2 will work better than a generic splice-it type) -Check for "flat spots" during operation of the AFM flap (See bentley for pins to bridge and resistance values to observe) There is a "capacitor fix" if this seems to be your problem. -Clean <underline>all</underline> grounds -Ground the AFM to a good ground (there is an M8 bolt hole on the back side next to the harness) -Inspect cap/rotor for carbon tracking -Inspect all vacuum lines for leaks replace as necessary
If that doesn't yield results then: -Check Idle stabilizer valve -Check fuel pressure regulator -Check wires -Check plugs Cheers,
