To my info P1181 is problem with fuel pressure on the common fuelrail.
It could mean you do not have enough fuel pressure on the rail giving bad performance by the injectors. They could not inject enough fuel given the compression pressure of the cylinders.
You would have to look at your high pressure fuel pump, or you might even have only a clogged fuel filter.
Or it could mean the pressure sensor on the rail is faulty. Then you must check it (variation of signal when starting, giving pressure) or the electric connections.
