hi all,
im a little stuck atm regarding the fualt on my corsa sport, head gasket went between cylinder 3 & 4 about a week ago, fair enough replaced the head gasket with a full kit, and had the head skimmed.....ran fine when finished, but engine light on
next day drove terrable ie rough and lumpy, got it on diagnostics came out with p0150 i think, map sensor malfunction. replaced the map sensor ran no differant, hunting up and down on idle not wanting to rev up
got it back on diagnostic. same fualt code on,
the car only hunts on idle when it is warm so i have been thinking EGR fualt causing map code to be thrown up? due to stuck open chaningin the pressure in manifold.....
was going to blank it off but wondered if any1 else has and how the car ran after
any help would be appriciated!!

Checked vacuum pipes as thats what mine done when i had a perished one. May have even missed connecting one back up? main one from the map sensor is the one that went on my old corsa.
