if this pic turns out right its the results of my 4 gas test before i planned to have my fuel injection cleaned?

 

I was glad the pic worked from my phone....

I wanted to have my mechanic run a fuel injection flush thru my
1997 XJ6 V.P. / 4.0 liter

I always try to be smart before taking my Jag to the mechanics...lol
So i suggested we run the 4 gas test before the fuel cleaning treatment and then run the test again after the fuel cleaning and wandering about the results?

I have only owned this Jag for 3 months.... and i have put her thru the paces and she has had alot of work done all around by myself.

Come to find out the system was nearly carbon free and my mechanic was stunned to see the results.... He said near perfect as when she rolled of the line in Brittan.... Short story... no fuel injector cleaning needed....and i saved $75...lol We both agreed the older man that owned the car put Super 93 oct. gas her whole life... cheers
