My 2000 S40 has been starting hard over the past few months. I drove it home today, and it won't start back up (15 minutes later). It turns for a few seconds, starts, runs at around 400rpm then promptly dies. The fan then engages and continues running for about five minutes. There are three codes (Coolant temp below thermostat regulating temp; Cylinder 3 misfire detected; MAF of VAF circuit low input). The car is not low on any fluids and has around 119,000 miles on it. I'm not sure where to start so any advice would be greatly appreciated. Thanks.

 

I think from my starting troubles [turned over but wouldn't start and fan run on] that I would try the temp sensor under thermostat housing. Fix my 2000 s40 1.9T for now at least. She was giving me sum strange codes, but the temp code was always first.
