99 S70 N/a #4 cyl no fire...wiring help
Hey guys, m y 99 S70 2.5 N/A has just recently started acting up. ROUGH startup and stuttering until warmed up. Here's what I found though, If I pull a coilpack connector off a cylinder, the rpms drop off as they should, all except for cyl #4. So I swap in a known good coil pack onto the #4 cylinder, and still no fire.
What triggers the firing on these distributorless ignitions?? As it seems there is no spark be sent to that cylinder??
