Hello again I HAVE A problem with my engine when driving on speeds over 120kmph and going down to 80 the car speeds up slowly its reaction is slow this happened after replacing oil I used to use mobil 1 5/30 but this time I USED LUEQY MOLI 5/40 IT SEEMS THAT THE CAUSE IS the CPS or MAF but the computer test shows no error codes and the engine is harsh could it be the oil and if it is does it affect the engine ( the car accelerates slowly and when you push hard the rpm stays the same and suddenly rises )
thank you

No, not the oil at all.

I would look at fuel pressure.

I would also look at the back pressure in the exhaust for a clogged cat converter
