Hi all! New to this messeage stuff, but been reading the info for awhile. Anyhow, I have a S70 with 150K and car is in excellent condition, been running like a trooper up until yesterday. All of a sudden I heard turning into our neighborhood the started to sound rough, like it dropped a cylinder. So far, I have out this:
1. All the spark plugs are fine
2. Disconnected coil packs one at a time and found 1-2 packs maybe have of an impact on the rough ideling.
3. All the wiring and grounds are fine.
4. Its not easy to get a coil pack immediately. (geesh!)
What now?
