Hi guys.The citroen berlingo is a 2001 model with KFW 1,4 engine.The customers complaint is sometimes the idle is unstable and hesitation on acceleration sometimes also.He left the car for further investigation.The symptoms that the customer tells me is very critical to have a direction where to look for,if there is no check light.From the scanner i had no codes and whent to the parameters looking for volt dropouts at the tps,because i believed that was the problem .Could not see anything unusual.So Pico came out and in 15 minutes the problem was solved.You could see in the zoomed file
