Hi,

I'm not a mechanic but this could be useful: https://clubjazz.org/forum/index.php?topic=6575.0

I would check hoses, for any obvious leaks or bad connection. Check the engine air filter too, is it dirty? You could also disconnect the battery for 30 mins and reconnect - that will reset the ECU. Have you got access to a OBD scanner? Maybe there's a fault code to work with.

Possible vacuum leak? check as mentioned above.
