Calling all Volvo Techs...new CAT.....worst problem 900 1991

Does the new converter pipe have a plug you can unscrew upstream of the converter itself? If it does unscrew it and see if the performance is any better with it out.

Is it throwing black smoke when it bogs down? If it does check for a leak in the turbo hoses. These can be difficult to find. I made a plug to clamp into the hose that I removed from the turbo and then adapted a Schrader valve so I could pressurize the system with 15 lbs of compressed air and found the leak in the hose that had evaded me prior to that.
