Hi all
I recently bought a 2003 ST170 (SVT) and have noticed a surging/ stuttering at ~60mph at around 2100rpm
Problem is more evident when in lower gears and revved higher e.g. 4000rpm in 2nd
I've checked for fault codes and came up with P1132 and P1158.
I know P1158 refers to a malfunctioning IMRC, and the P1132 to the O2s reading lean.
Would anyone have any idea to a solution to this?

Any help is much appreciated
