So as you may have guessed from the title, I'm having some fun with my car.
It's a 2001 Legacy B4 RSK BE5 Rev-D. I had an issue with engine pinging a couple of months ago, and have run a bit of octane boost since then, which seemed to fix the issues.
But, on the commute in this morning, I was in 4th and braking as the traffic slowed. As we started moving again, I popped it down to 3rd, and as I released the clutch, it just started juddering (a bit like if you are in too high a gear, but I am sure I wasn't - would have been about 50ish). It actually felt like it was going to stall, and I noticed the check engine light. I didn't notice any noises other than the "wrong gear, moron" engine protest noise.
So I shifted to 2nd I guess out of instinct, and there was just no power and the check engine light was on. The light clicked off, and power was there again, until the check engine light came back on and power was lost again...
There was nowhere to pull over due to the highway upgrade happening in Welly, so I just babied it to town. It came right for a good 10 minutes, and I actually wondered if it was just a passing issue. But when I was driving in the carpark (low speed, lots of clutch) it started playing up again.
So its now sitting parked, I'm at work and I know I have to get home
Does anyone have any idea what it could be? I'm thinking it may be related to the ping that was happening before, but I really don't know. Are there any common problems that would be worth checking first?
The thing that's making it even more difficult to understand is when the check engine light is on, the power is gone. I can't tell if it is the loss of power causing the check engine light, or if it is something quite minor that is clicking the check engine light on, putting it into limp mode or something... does it even have limp mode?
Any advice would be great. I'm planning to "limp" it home early today to avoid the traffic. Hopefully she makes it
