ok so i was the one with the problem where i changed the pcv box and a few days later i lost all acceleration beyond 1400 rpm anyways i changed all vacuum lines and checked all hoses still nothing so i took it to a volvo mechanic he checked it with the volvo diag software and found nothing still no check engine or warnings or codes so he kept it for awhile checked the etm its fine checked the turbos there fine did a boost pressure test everything there is fine now hes checking the fuel pressure but so far hes at a loss as well as i am what is going on?

just had the trany replaced year ago plus this happens also when its in neutral not just drive and any trany related issues normally pop up on dash warning

Sounds like a significant vacuum leak on the intake side, check the Intercooler hose fittings all the way to the ETM, that thing is introducing air past the MAF or you have weak or irregular fuel pressure.

Even though it checked OK, still sounds like limp home mode from ETM. We had intermittent ETM issues on S80 & S60, both at about 80-100,000 km, (50,000 -62,500 miles. in each case Xemodex exchange fixed issue. On the S60, after fitting needed computer reset on VADIS.
