please help diagnose this problem post head install refer to this post for background information
here is exactly what happens. everytime i start the car, whether the engine is hot or cold, the car stumbles and hesitates for the first 3-4 minutes. after that its fine. i can get in, start the car, and drive around dealing with the hesitation for 3-4 minutes and it goes away, or i can start the car and wait 3-4 minutes to get in and drive and it drives fine. after those couple minutes the car drives perfect, both at part throttle and wide open throttle
this makes me this there is something up with the open loop tuning of the car
i scanned it on atap
here are a couple wot throttle runs
does this look ok, i dont know much about atap
also what can i do about the 3-4 minutes on stumbling upon starting the car. can that be fixed with tuning
thanks for any input
