V70: Engine - 2007 V70 Slow Down or Shift Up, Misfire, dies at various spe

Wayman · Jul 23rd, 2016, 23:25

2007 V70 2.4L. 140k miles.
Original fault of shuddering "Slow Down or Shift Up" corrected with replacing faulty ignition coil packs. The V7P occasionally dies at various speeds below 40 MPH, especially at a accelerating from a stop. The dying was occurring before the coil pack replacement.
I have read that the MAF and throttle body wears about this mileage causing the shut off. Essentially looking for verification before I shell out the money for a new throttle body and MAF.
Notes:
Idles at 1800 RPMS on start up then backs down to 800 after about two minutes.

I'd be looking at the Idle Control Valve first. Everything seems related to a poor idle, where as the MAF and throttle body would show more symptoms, ie under power.
