My engine loves to act up...
I was in my car, with the the battery on so the Air was running, as well as the radio, when I then tried to start the car. The car started with a bit of a jolt, and ran at 100-200 RPM's for about 2 seconds before bogging out and dying. "Weird" I thought, so I tried it again. Same thing. Last time I had this issue, a big hose in my vacuum line had disconnected itself, so I went to check on it to see if it was the problem, it was not. I inspected about all I could in the engine bay without jacking it up or going under it, checked oil, etc. Nothing super obvious was causing the issue. So, I called my dad, and around 30 minutes later he was there and looking over the engine with me. We started the car, and it started running pretty much exactly like it usually does. 900-1100 RPM's that is. Drove home fine, and it is now sitting in the driveway.
The facts I know:
I got the diagnosis of piston ring failure around a month ago, as well as some super low compression in cylinder 2 (around 50 compared to the 135-140 on the others) so I suspect that is to blame.
The battery wasn't the issue (could have been the starter though)
The oil was full
No severe leaks of any kind
Temps and Oil Pressure were exactly like they always were, the needle being just under the middle line on both.
Im pretty much just looking for a diagnosis here. I don't even have a clue what might be causing the issue due to my unfamiliarity with the engine. I will also be buying a compression gauge to measure the other cylinders compression.
I do have an extra coil pack handy, so I might end up swapping that around at some point (if it turns out to be the culprit).
Also, see the video in the following post to see my engine bay, and hear the car running after it made it home (the engine was running normally at this point, but I thought that there were some strange noises coming from something internally. I'm chalking it up to paranoia)
