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.
