Hello Volvo forums, and marry christmas
I own a volvo 940 estate from 1996, with a b230fk engine
the last couple of weeks my volvo had a weird issue
everytime i try to accelerate its stuttering and losing power (kinda feels like its hitting rev limitor, without actually doing it)
its idles a bit rough, but if i ease the pedal there not a problem,
i thinks its everytime its trying to make boost, sound like its fuel cutting or something like that
i changed the sparkplugs, and looked for a vacuum leak, but cant find any
do you guys have any suggestions of what may cause the problem?

thank
Magnus

 

Boost? Is it a turbo? Not familiar with a 230fk engine.
Is the check engine light on?
Have you ran the codes in the OBD system? This may give you a clue...
Wild guess on the info given, may be the MAFS is bad (mass airflow sensor)...

 

Yes its a turbo
no engine light
