Hello everyone - I'm a long time lurker on this Forum , and have gleaned a lot of useful information and knowledge from posters on here :worship:
I am a fairly recent convert to watercooled 911s , having owned aircooled cars , and 924/944s for years - Inow realise what I have been missing
Anyway , my issue is with my 2006 manual 997 C2 , in which I have covered about 8,000 mainly trouble -free miles in the last 18 months.
About a month ago , the EML came on and the car misfired badly at the end of our drive , which is a fairly rough stone track , two days in a row at exactly the same spot , where I stop to join the road.
Both times I turned it off , restarted and drove 10 miles or so with no issue , and 8 hours later returned home, again with no problem.
We then went on holiday for a couple of weeks , and this weekend , I started it up - all fine - got to the end of the lane - and same thing again
:x . Unfortunately this time , restarting had no effect .
I connected it up to my code reader and got cylinder misfire codes on cylinders 1, 2 and 3 , and also code P0660 - "Intake manifold tuning valve control circuit/open bank1"
I cleared the codes , restarted the car , and the EML was back on almost immediately , throwing out the same codes.
Can anyone shed some light on my next steps - I'm not even sure what an intake manifold tuning valve does ?
Any help would be gratefully received.
PS I replaced plugs and coil packs about 4000 miles ago
Thanks
Mark
