Hi guys

Had a customer call in on friday saying her 04 ford focus 1.6 had lost power on a few occasions, not cut out but slowed down enough for her to have to pull over . emissions light had came on as well .
Code present was p060a control module monitoring processor performance. Being busy on Friday ive asked her to bring the car in this week so i can spend some time on it and also find some info on the code as it isnt listed in my trouble codes book or autodata can anyone help or has anyone dealt with this code before.

The car had pre cat 02 sensor fitted by me about three weeks ago in case its worth mentioning

thanks in advance lee
