Question:

it’s the spark plugs, these engine only like a certain kind and if yu pick the wrong one you kill the plugs easily.  i had the prob twice and haven’t for a long time now.  you either have the wrong gap or you flooded the thing and killed it either way one of the plugs mostlikely went dead and needs a fixen.  take it to the dealer they have an upgrade plug for these engines and put them in correctly (i hope).  if you feel the engine putter at mid to low range then you killed a plug and your dumpin fuel down the exhaust. checkem good new comer joey – Hide quoted text — Show quoted text – > Does anyone out there know exactly what causes the "check engine" > warning light to go on and stay on.  I have a 1996 Explorer (V6) and for > some odd reason ever since I changed the plugs on it, the dam light just > won’t go out.  I know this has something to do with emissions, but I was > wondering if it has this happened to anyone else and if it has what did > you do to fix it.  I wonder if it has anything to do with spark plug gap > spacing.  If anyone has an answer please let me know.  Thanks.

Greg: The stamped-ring encoder works on your car.  The system works by reading the variations in the flux density as the ring passes the pickup.  I had a long discussion with Century/Raybestos on this for a reader in Germany who was tearing his hair with the same problems. Solution is the current replacement stamped-ring ABS rotor, they said.

Response:

Thanks Dr. Bob! After lengthy examination at the parts store, we came to the same conclusion and found that the new rotors would fit.  After installation, a hard braking in the gravel alley behind my house proved that the stamped-exciter rotor works just fine. — – Hide quoted text — Show quoted text – > Greg: > The stamped-ring encoder works on your car.  The system works by > reading the variations in the flux density as the ring passes the > pickup.  I had a long discussion with Century/Raybestos on this for a > reader in Germany who was tearing his hair with the same problems. > Solution is the current replacement stamped-ring ABS rotor, they said. > And it was… > dr bob

Does anyone out there know exactly what causes the "check engine" warning light to go on and stay on.  I have a 1996 Explorer (V6) and for some odd reason ever since I changed the plugs on it, the dam light just won’t go out.  I know this has something to do with emissions, but I was wondering if it has this happened to anyone else and if it has what did you do to fix it.  I wonder if it has anything to do with spark plug gap spacing.  If anyone has an answer please let me know.  Thanks.

Response:

Heres the list I’ve made: 1 – bad/dud plugs 2 – spark plug wires (really easy to screw up when changing plugs) 3 – O2 sensor going out / needing to be cleaned 4 – MAF (mass air flow?) sensor going out / needing to be cleaned 5 – cat damaged (on newer Explorers (ECC-V)) 6 – something deeper, such as injectors, spark distribution (eletronic or mechanical), computer damaged, wiring problems, etc etc etc. I’d go through and do the simple stuff first, especially wear items like plug wires, cleaning the MAF, etc etc.  If that doesn’t work find an error scanner and see if it gives you some clues.  If you’ve still got the old plugs you may want to try putting them back in and see if the problem goes away – I’ve had bad plugs before (thank you AC/Delco).

I have a ‘94 Explorer with 120K miles and it need new brakes.  I have to replace the rotors. Problem is, the dealers and parts stores only stock a rotor with a slotted ring ABS encoder.  My rotors have a toothed ring pressed into the bottom of the rotor hub.  I beleive there was a mid-year engineering change. Can anyone provide me with a part number for the correct rotor with the cast-tooth encoder rather than the stamped-ring encoder? —
