Hey guys When cold, sometimes my car will start to hesitate/lag/jitter back and forth in second gear/third gear. Usually the problems solved by either just driving at 40km/h (it comes on usually at 50km/h) or changing up a gear and revving. If it helps I think my AFM is clogged up with gunk from the oiled filter (will get new non-oiled filter installed into the fender soon, a long with cleaning the AFM and throttle body), and I need to get codes read from supercheap. I think it could be either AFM or spark plugs/coil packs? I have watched boost gauge stay on and it doesn't show any loss in boost. I've read online that it could be a BHG... but how could a blown headgasket cause a hesitation problem? I don't hear any backfiring or misses.

Hey guys, Had my 2001 GG9 wagon for a few months now and has always had a problem with cold starts. On warm days its not so bad but cold or wet days its an issue. When starting from cold it starts and idles fine. But when you then go to drive while engine is still cold it hesitates (loses almost all power/drive) from 1500-2500 rpm... Once it's warm the issue seems to clear itself up. Had a look on the internet and this seems to be a common issue. But they all seem to have poor idling and suggest a huge list of things it could be. Is there an easy way to find out before I go looking at everything? Seems temperature reliant so maybe coolant sensor? Or throttle sensor? Any help would be appreciated. Thanks.
