Okay fellow TB owners. I've got another problem with my 2006 Trailblazer V8.
I changed the plugs and wires about six months ago when multiple misfires started. It ran awesome up until two days ago. My wife calls and says it's running rough again.
Bam. Cylinder 1 misfire.
The next night she says the oil pressure kept dropping to nothing and the HUD told her to stop the engine.
Turns out the oil was really low. We've been busy and I spaced checking it. All my fault. I filled it back up and starting trying to diagnose the misfire.
The coil pack is fine. The misfire didn't follow to cylinder 3 when I changed the connector. I pulled the plug on #1 and it was wet and fouled. It had a lot of carbon on it too.
The oil pressure is still dropping to nothing when driving.
It's going to my mechanic tonight, but I need ideas.
