Liqui Moly 4066 Air Flow Sensor Cleaner 200ml & 1803 Injection Cleaner 300ml

T’ wife’s 2012 Fiesta Zetec 1.25 was running really roughly. Hunting at idle, sluggish acceleration, woeful mpg. I used the combination of Liqui Moly 4066 maf sensor cleaner and Liqui Moly 1803 injector cleaner, which did a great job of sorting out the problems. Result is much smoother idle, more power and 40+ mpg instead of 25 mpg. It may not work for everyone, but it worked well for me.

I've added this Liqui Moly 4066 bundle, with 1803 Injection Cleaner into my petrol tank, and sprayed it into the air intake. But my Mercedes A180, which is basically a computer on wheels, cannot detect any improvement in either engine performance or fuel consumption costs. So it would appear to be a waste of my money, which I could have spent on buying some more petrol, which definitely would have improved my fuel consumption costs. I'm disappointed in myself for believing the sales talk. Not recommended.
