A couple days ago I drove to run an errand, my 1998 V70 T5 ran fine. When I returned to the car it started but idled roughly at 600rpm. I tried to apply throttle but it was unresponsive. After about 60s I was able to use the throttle to slowly build more rpm and "clean it up." After that, it ran fine.

Does this jog any ideas with the forum members? I suspect that it is related to fuel metering or delivery.

Update, it did this to me again last night. The car was fully warm, and without warning at 30mph all throttle response disappeared. I barely maintained momentum and got off hte road. The car idled again at 600rpm. After maybe 30-60s, it cleaned itself up again. Since then I've driven 3 times and it's been fine.

Has this never happened to any forum readers? My thoughts on this are:
1. MAF
2. MAP?
3. TPS
4. Fuel pump?

 

Solved. Thanks to Auto Zone for reading the OBD code. MAF sensor.
