Causes of Engine Misfires
Even after changing the spark plug wires or coils, the engine continues to misfire.
How to Fix Engine Misfires
If the coils have been changed, it could be the fuel injector, but on the 4th gen Escalade it’s likely a lifter that has collapsed. The 4th gen Escalade engine has a system that will go into the 4-cylinder mode where the lifters collapse. Sometimes the lifters stay collapsed and sometimes it’s because the oil is not changed regularly. With the lifter collapsed there will be no compression in the cylinder, causing a misfire.
If the problem is not with the ignition system or the fuel injector, the heads will need to be removed.

On the 4th gen Escalade, an audible warning and haptic motors in the seat will trigger when driving too close to an object. The motor and its wire on the driver side closest to the door can flex from movement over time as the seat wears from use. This can cause them to break and trigger the warning light.

Replace the motor and run the wire
