There are NO Recalls that I can find, but there is definitely a poor design flaw. This engine set up allows water to contact the coils, thereby causing them to fail. According to my mechanic, who I do trust, there is no way to shield this water intrusion.
I used to not worry about driving thru standing water, as I have a tall vehicle. Now, I Know, whenever it rains, I MUST BE CAREFUL, not to splash too much water on the roadway, or drive thru any standing water, if possible, or I will be in the shop in 1 to 2 weeks with a failed spark plug coil.
We just had a tropical storm nearby with lots of rain in our area, and 1 week later, I need to replace one of my coils- skipping and sputtering F150!
Your truck does not have ignition coil. Instead, it has coil packs. The 5.4L has eight coil packs one on each spark plug. The 4.6L has two coil pack blocks 4 on each block.
under the coil packs and the coil packs are connected to the spark plug wires
Separate ignition coils for each cylinder. Commonly known as direct ignition.
The ignition modulator sits directly behind the coil packs. The coil packs mount onto the ignition modulator.
three
you dont
ignition control module
your buick is ovisley not super charged with coil packs because its looking for a cam sensor
check your plug wires, then your coil packs, then your ignition module.
both the 3100 and 3800 series engines have the ignition control module mounted under the coil packs. remove the coil packs and there it is.
The ignition coil is down between the firewall and the back of the engine
A 1997 Jeep Grand Cherokee has one ignition coil.
