QuestionPlease explain the steps I would take to replace the ignition coil in my 1996 ford explorer. (2WD, 4.0 engine). My engine has been misfiring; so, I took it to the dealer to get their diagnosis since I ran out of troubleshooting options. Thanks!
AnswerDisconnect battery ground cable (14301).
Disconnect fuel charging wiring (9D930) from ignition coil (12029).
Remove spark plug wires by squeezing locking tabs to release ignition coil boot retainers.
On Explorer and Ranger vehicles equipped with air conditioning, remove air conditioning tube-to-plenum bolt and move tube enough to gain access to ignition coil bolts.
Remove ignition coil bolts and remove ignition coil.
Installation
Install ignition coil. Tighten ignition coil bolts to 5-7 Nm (45-61 lb-in).
On Explorer and Ranger vehicles equipped with air conditioning, reposition air conditioning tube and secure. Tighten air conditioning tube-to-plenum bolt to 26-32 Nm (20-23 lb-ft).
Connect spark plug wires and connect fuel charging wiring to ignition coil.
NOTE: When the battery voltage is removed from the powertrain control module (PCM) (12A650), all learned values will be cleared and reset to predetermined values. When battery voltage is restored to the PCM, the vehicle may exhibit certain driveability concerns. It will be necessary to drive the vehicle to allow the PCM to relearn values for optimum driveability and performance.
Connect battery ground cable.
