Well I got to the shop on base today.. first thing I did was a compression test. Low numbers across the board. All were around 100 psi and #3 was at 110. I believe I may have found my issue.. haha either way I'd definitely want to rebuild this now. Or throw it in the bin... one or the other. This would explain the "oily" look to my pistons.
Keep in mind my lack of resources.
I tried to do a leak down test just to put my mind more at ease by making sure it was leaking past the rings. The shop didn't have a proper leak down tester so I tried to hook the compression tester up to shop air but the fittings were different. Go figure.
Did a "power balance test" by unplugging my coils one by one. Each one made a difference even while it was idling like crap. So I don't believe it to be a coil.
I saw a ground directly behind the 4th coil. It was plugged into a metal bracket on the firewall which was also bolted to the same bracket on the other end of the wire. I didn't look into that any further. I figured it looked untampered and thus correct.
This is when I called it quits. I might do a compression test on a good running sr just to make sure the gauge I was using isn't crap, but I'm pretty sure it was fine. I'll definitely start keeping an eye out for another motor or start considering a rebuild.
Has anyone else had low compression numbers yield these symptoms? And a rebuild alone resolved it?
Just to answer your questions Kingtal0n.. thank you for the response btw. I don't have an alarm or turbo timer. Yes, my igniter is mounted (lol) and it is bolted down securely. Everything is stock except for the s15 turbo. ^_^ I'm not sure what model ecu or harness it's using. I could check the numbers if it's really that pertinent, but I think the compression numbers speak the loudest. Under the valve cover looks fine.
