Title: Short Term Fuel Trim always at 99,2%
Post by: crkest on March 12, 2017, 05:19:36 pm

Hi,

My GTI of 2005, DSG, red Tornado with trend(tendency) in surconsommer a little.

My father has a scanner OBD2 with the software EOBD-Facile (a french software) !

And actually, we notice that the correction STFT (Short Term Fuel Trim) is always 99,2 %
What makes that it enriched always mixes him.

I changed both oxygen sensors , nothing can be done!
As a result, it is necessary to look somewhere else!
MAF, injectors, catalyst?

Anybody has already had this problem?

Merci

Sorry for my English !!!
