Looking for ideas on 2002 Volvo S60 184,000 miles

[Sbolser]

Asking for some ideas my check engine light came one said MAF sensor I have replaced it but continue to have problems. Starts fine but then will hesitate sometimes it goes into limp mode when I give it gas nothing happens. Pull over turn it off then I am okay till it happens again. Has happened at lower speeds hasn’t happened at highway speeds yet. Stopped by a shop they came me a few ideas. Check the temp on catalytic converter it was at 220 said if it was cold that could be it. He thought maybe fuel pump, fuel injectors,vacuum leak, fuel filter. I replace the fuel filter about a month ago. Had misfire on one a year ago replaced that then another misfire on five I replaced that about three months ago.
Need to make a trip next week and want to fix this just don’t want to throw parts a it. Any ideas?

Have you read codes? Has the ETM (electronic throttle module) ever been replaced? With the miles it would be due for replacement.
