My 1999 SAAB 9-5 wagon 2.3 LPT has no guts and barely makes it up a big hill. I purchased a used turbo thinking that was the problem but a Mercedes mechanic told me the car drives like a blocked catalytic converter. Online comments indicate the former could be caused by the latter. Today the MB mechanic will be dropping the catalytic converter to see if that makes a difference. And will also be doing a pressure test (?).
Anybody else face this situation or have any ideas?
