Good evening guys, I'm after a little help if possible so here goes.. I own a 2008 rrs tdv8 HST with 110k miles and I've recently been getting a very light misfire every couple of seconds on tick over. But it seems it's getting worse as low down in the revs it's very slightly down on power, I hooked it up to my friends snap on diagnostics and the following came up.. I know I've got to change injector 7 as it's out of range but could anyone shed any light on the rest of the faults? Egr values look out aswel as the air flow meter readings and intercooler temp sensors are out of coralation.. there are no splits in the top boost pipe hoses and all other pipes seem to be intact and connected securely, if anyone could help me with narrowing this issue down I would be very grateful!!
Thank you
Tim

Had similar list of faults when one of my injectors was on the way.

The ecu is trying to compensate so will throw up all sorts of weird values. Sort the injector first and then clear faults and then check again.

If you do a egr valve do both at same time as by the time you have got to the first one you might as well do both.

I did the EGR valves first and the renewed power pushed the faulty injector over the edge and it died  TDV8 now with extra grin factor thanks to Alive Tunning: Gone but not forgotten

Hi Rob.. thanks for your reply mate. I've ordered an injector and going to see how it goes from there, as far as I can see the egrs both look new but I can't tell if they're good quality or copies, looking at the air flow readings I'm thinking it's quite possible an egr is sticking and that would explain the difference in air flow and temp values, what other symptoms did you get mate? My eml light isn't lit either

EGR valve would stick if I booted it with Engine System Fault message. General lack of power

Ignition off and back on would clear it but I drove it like that for a year.

Swapped the two EGR's out for new ones and it was great for a month and then the injector started failing with the increased demand from the engine. Got all sorts of strange reading at that stage on AA patrol laptop and mates Snap On Sonus as per your pics
All related to injector balance and some air flow I think TDV8 now with extra grin factor thanks to Alive Tunning: Gone but not forgotten

I do believe there are no cheap EGR valve copies, only original ones are available at around £135/£150 each. 07,TDV8,Black, Black Heated leather all round, Rear Entertainment with Headpones & Remote, TV, DVD, Pure Dab Digital Radio, Sidesteps, Adaptive Headlights, sunroof, now working fuel burning heater )))
