Pierre has been playing silly buggers again this week. After fitting a new injector it ran nicely again - for a couple of weeks.
Thus week it seemed to have a big flat spot just where the turbo should kick in, then the turbo kicks in higher up the rev range than it normally would.
It has got steadily worse, and yesterday threw up fault code 2263 - turbo boost issue.
It could be the second hand turbo I fitted at the beginning of this year is on the way out, or it could be something associated such as a blockage / air leak / vacuum / sensor / etc. etc.
Will start having a look at it later, but not really sure how to diagnose the problem.
No smoke or oil being chucked out the exhaust (yet), so Im slightly optimistic it isnt the turbo itself.
I havent (yet) had the ECU coded for the new injector, but I doubt thats connected to this issue.
I hear the Swan Vestas calling to me once again.
