Hi all
I need some advice I had an OBDII reader on my 4.6 range rover as it seemed to be running rich and had a rough idle. This turned out to be the MAF.
My OBDII reader showed the fuel trims as
Short Term - 25 Lean
Long Term + 25 Rich
I booked the rangie in to have the fuel trims reset at my local stealers. I got the vehicle back today and it still did not seem to be running properly
When I put the OBDII reader on the fuel trims still read
Short Term - 25 Lean
Long Term + 25 Rich
Would I be right in assuming that they have not reset the trims, but have just reset the fault codes?
The vehicle is running rich 9mpg round town, where as 2 month ago it would do 13mpg under the same conditions.
