Hi
Took my 986 in for a minor service at a porsche dealer, as recommended by them.
The car was running perfectly I'd just done about 1000 miles in 6 weeks no problem.
They did the service and found two permanent codes for the o2 sensors stored on the dme
along with an oil leak. I suggested they check the oil leak by cleaning the engine and report
back. No oil leak was found, but the coolant hose and front engine mount had problems and
so they were replaced. The o2 sensors were not replaced due to the extra cost.
Now I come and pick the car up, and I can't even get it out the car park! It has a judder/stutter
with white smoke and then feels like it's about to stall, not in a good way at all.
Question is would this be caused by the o2 sensors (1-3) and (4-6) giving codes 10 and 18?
It looks like something has happened while it's been in for a service because it was fine
when I took it in. Would the judder /near stall be caused by the MAF instead or a lot of
other possibilities?
