How annoying! My volvo 940. She comes on boost and pulls slowly up until 3500ish, then shudders and the boost completely drops off, and then I've to stop accelerating in that gear. It's stock bar the airbox is off and there's gauze over the Air flow meter. Is there not enough restriction or something? Or is it a boost cut? Or or??? I've no clue bout volvos, please help, it's stopping me from drifting! Thanks guys
Its a volvo......!
Check for boost leaks frirst of all lad...!

shagged fuel pump as in its not able to supply enough fuel on full boost
When were plugs last done, could be seriously fouled!
Did you try the manuel boost controller, i kno u were looking for one?
check the tank if its been lyin up for a while could be ful of sludge and could be fuel pump also
also, forgot to mention, there is some kind of a warning light up on the dash, like a triangle..possibly an electrical symbol...could this have anything to do with it? cheers guys. its wrecking my head
Limp mode!!!!
yeh i started to think about that earlier alrite...how can i get it out of limp mode?!Quote:

i havnt got one :D
Speaking of which though, myself and darragh were tinkering last night, took off a pipe on the hot side of turbo, which went to some sensor and back to afm. blocked it off and drove it, didnt seem any differant. but it was only after a while the light came on. ie, an hour or so.
Mechanics, i need thee in cork! ha
That light is definitely lambda! So it probably is triggering a limp mode or something to save itself after we went fiddling with the branch!!
reading on the volvo forums, when that light is on, it doesnt actualy do anything...bar tell you that something is up with it! I must check the inlet pipe problem that aparently is common on them...its crumples in under ful boost once hot!
i want to go wreck itttttt come oooonnnnnn!
Is it an orange light with a green centre??Quote:
