Engine light came up, took to autoshop for computer reading, came up as 02, 2nd chamber misfiring, vehicle very jittery. Chnaged spark plugs, oil, and checked coil packs. Switched 2nd chamber coil pack with 4th chamber coil pack, erased computer reading by unhooking battery for 2 minutes. Restarted, still jittery, ran at 35 miles per hour, engine light comes back on, reading states chamber 02 misfiring, even with switched out coil pack. Checked wiring, nothing looks bad on wiring for coil pack. Auto still jittery and when driven has a lurching/hesitating pull, on parked, jitters to a very low idle. Why would it still show 2nd chamber misfiring if all wires look good, spark plugs new, oil changed and coil pack switched out? Thank you kindly.
have the same problem?
