my Volvo 850 GLT idles fine until gets warm. Then erratic idle, then stalls. Symptoms upon trying to restart feels like MAF. But if I let sit 10-15 seconds, then restarts fine. My sister gave it to me and has had a lot of work done. Dealer had it for weeks and couldn't figure out. Doesn't show any codes either. Please help so I can stop putting miles on my '86 Turbo Regal T-Type!!
Might be the Crankcase Ventilation System Failure (PCV/Flame trap), hoses get hard and brittle and cracked causing idle issues.
Maybe throttle body or MAF related?
