BlackCoog -- Make sure to try the test situation where the bucking disappears. Leave your car all night, dont use it. Then start her up and let it idle for only 15 seconds then take off, dont wait any longer! You want to drive her when shes cold. Then try some accleration tests, esp in 3rd and 4rth where you would normally stutter -- you should see it not present. This works every time the engine is totally cold. I have tried this MANY times and just cant get over it, how does the car NOT stutter when in open loop/engine cold but then do it when starts to warm up and esp at close-loop/operating temp?? These MaF tricks are only band-aiding thr problem I think. Trust me, I am researching this extenesively and trying anything that might give me a clue. Good luck. More later.
