2011 RCZ 156 THP

[sgl3112]

I have a 1.6 THP that shudders when cold idle and flags a P0016 error, sometimes I get P0087 also. The HPFP was changed recently but the idle issue is new, once warm it runs fine. Any body had a similar issue and can advise what the fix is?

P0016 is Cam/ Crank position Bank 1 sensor A Cylinder misfire?
P0087 Fuel rail system pressure too low
Cold start temp issues have been known to flag up the atmospheric sensor problem which is in the door mirror & can affect start up (lumpy tick over) but I would get the fuel rail pressure checked out first
