This morning was the first time I've really driven my SJ any meaningful distance since Wagtail and I've noticed that she seems to lose power when I'm accelerating away from junctions and such. Seems to happen at about 15mph in first, 25 in second and about 40 in third so I'd guess about 4000 revs. Feels like you're running into a rather spongy rev limiter on a fuel injected engine.

I think I might be dropping a cylinder. I've not had chance tonight but I'm going to take the plugs out and see what they're like.

As it's now getting colder open up the hot air feed? Might be getting a mild case of carb freeze

I've already got it on the hot feed after the cold spell a few weeks ago.

Fuel filter?

I had an issue with mine before losing power if I got
In higher revs or if I was trying to accelerate. It was the
In line filter clogging and collapsing.

Fairly certain it's not that, but I'll check. I used to have problems with that but I solved it. The loss in power isn't as abrupt as when the fuel lines got clogged.

Worth checking your points gap and condition as well, it was always the first thing I would check on mine.

Well, I cleaned and gapped the plugs and checked the points (which were fine). As I was putting the plugs back in I noticed (not sure how I missed it) that the hot feed pipe had collapsed where it routes over the top of the engine. I'm guessing the vacuum caused by the engine made the old decrepit pipe give way and so it was suffocating the engine. I'll find out when I go for a run later today if it has fixed it.
