Hi folks,

Had a scan done on the my wife's car as I was not happy with the consumption and overall performance. Car felt a little bit lagging in throttle response (or it might be that I've gotten too used to of my S4 :sunglasses:).

The scanned showed that Cylinder 3 was slightly out and fluctuating between 1.8 and 3 mils per stroke. I put the cleaner in as instructed by my local indy and he thinks it should be fine. Car does feel smoother after that (hope it is not phycological) I just thought I'll ask you guys as well if there is anything I need to be wary of (I am thinking injectors, would it or could it have any effect etc)

Thanks,
 
What cleaner did you try? Did you scan after? - if no improvement; could well be a seal.

Another option might be liquid moly diesel purge which is pretty good.

Cheers @JonSline. He used Wynns Formula Gold Diesel System Treatment. He has just come back and said that it was cleared after a little while. He is coming over to change the lower linkage arm Tuesday next week.

Just searched Liqui Moly and was wondering there is Diesel purge as well as Injector cleaner and was wondering if I should order both. I can try either of the one you guys recommend before his visit on Monday and ready for the second scan.
 
Neat diesel purge for a bad problem sorts it out. Best out of a can, few vids on YouTube on how to do it. New fuel filter after.

If the fuel out of the filter is black then it can be leaking seals on the injector/s

Bit of liquid moly will sort out carboned up injectors, bit of ZX-1 and an oil change does the world of good for economy.

Worth checking things like torsion value, temps sensors and maf/map sensor values as small variations on each of these will lead to poor performance and economy.
