Hi everybody my 2011 Volvo s40 has an strange problem after he has been working for an hour or two starts to lose power i step the foot on the gas and doesnt accelerate as 1 hour before
it also starts having the problem faster if I use the AC
has no codes no check engine light or anything in the cluster, temperature shows fine at it but I don’t trust it cuz I feel the engine a little bit hotter than usual oil coolant etc is brand new
The car works perfect but thats his only problem
what could it be Coolant Sensor? O2 sensor ? It is a manual 2.0 liter 4 cyl Aspirated petrol engine (Volvo B4204S3)
thanks before hand

Clean the MAF sensor and throttle body and change the engine air filter. Also, load test the battery and alternator.
