1995 Volvo 850 high idle [vacuum leak at right side vacuum takeoff] Topic is solved

[fantajuice]

My Volvo managed to develop a super high idle after swapping out shifter cables.

With swapping out the shifter cables I also found multiple turbo leaks, including a split hose and a cracked exhaust manifold. I've done all that, all hoses going to and from turbo have been checked.



Video included is exactly what it's doing. With a cold engine the idle is perfect, as soon as it gets warm it spikes up. Unplugging MAF it'll fall down to normal levels but only when standing still, when the car is rolling they're up there around 1500RPM.

Is the MAF sensor cooked? Anything else I should check?


Solved - vacuum line behind the power steering thing.

Well done!! When these cars start to give weird issues like this in the engine area, it often ends up being air leakage somewhere.
