ACT = Air Charge Temp. sensor.....make sure it's connected, it's between the #5 and #6 cylinder runners on the lower intake.........

Sure.....

98 at KOER means the system will not allow the full KOER routine to run until code 54 is fixed.

Code 85 = CANister Purge solenoid circuit.....is it connected or was it removed deleted.....I mean the solenoid on top of the canister filter shown below......



For code 95, clear codes first and check if it shows up again.....FYI.....Code 95 possible causes are:
[ul]- Inertia-fuel cutoff switch is open (when inertia switch is part of the primary or "relay activating" circuit)
- Open wire between the FP relay and ECM pin 19 (FPM signal)
- Bad FP ground
- FP relay stuck closed (FP on all the time even when ignition is off)
- FPM signal wire shorted to VPWR
- Faulty ECM

i checked the ACT but its located in front of the #1 injector i guess someone had it that way on the explorer intake, i'll change that sensors and see what happens
