As in the title my 1.8 Astra struggles to get going - losing power and juddering alot - for about the first 5mins when started from cold.
I cleaned out the throttle body a couple of months ago (which sorted another problem i had), and i'm not getting any dash lights coming on.
With pedal test i'm getting fault code P0170 (Fuel Trim Malfunction) which a lot of people are saying often relates to Air flow meter.
However, with the problem being predominately when the engine is cold, i'm thinking possible coilpack?
Anyone else had similar problems or got any ideas what to start with?
