Check this out
Its been going on for maybe... a month?
I noticed originally when the vac hose was off and I couldn't work out why it wasn't returning to idle, hovering around 1200rpm instead.
After a week or two I noticed the vac/boost line had popped off, put it back on all good.
No observable issues in normal driving, just this @ around 1500rpm.
I had thought the slightly shakiness just off idle was simply old, stuffed engine mounts...
But this is symptomatic of something else entirely...
Once again, the graph represents me trying to hold 1500rpm in neutral.
Start: The revs hold then suddenly drop to around 1200-1300rpm and the engine shakes from side to side.
Giving it more acc gets it steady again then back to Start.
I'm hoping for even more opportunities to improve my Lib whilst fixing this ahhh minor issue lol
