Because I`m interested (Its how you learn stuff) and trying to find out for her whats up with it, ok with you?

This symptom could be a lot of things. Bad MAF. A fuel line inside the tank could have come loose. Or, it could be something bad inside the engine because 4200 is right where the variocam kicks in...

Tell her to get it into a reputable repair shop asap.

Try unplugging the MAF then see if it still has issues with power past 4k rpm. If symptoms disappear, the MAF is the culprit.

Hi,

Possible MAF issue, or maybe O² Sensor. Another culprit could be the Fuel Filter. Depending upon mileage, he's likely due. It may flow enough to satisfy demand under 4500, but not capable of supplying the added fuel required above this mark...

Happy Motoring!... Jim'99
