Hi
Ive just fitted a dbilas inlet manifold to my astra, ive then driven it for 80+ miles to let the ecu adjust
and when i push it harder i get one of the following error codes:
1220 = Cyl.8-Fuel Inj.Circ. Short to B+
1221 = Cylinder shut-off exhaust valves Short circuit to ground
1514 = Intake Manifold Changeover Valve2 circuit Short to ground
What is causing them?
