Now this all assumes your condition as described is not a trans shifting issue, which would require a tech to road test and determine what the condition is. This really should have a full scan done to look at the tps operation and maf readings, if fp is good and it is found the trans is not the issue.

my buddy is a mechanic and he scanned it and drove it and he said the tps is now set in the right range the tranny is shifting correctly but the cross counts for the o2 sensors are low and the car is burning rich.. he said change o2 but it wont effect the hesitating.. when i brought car home i tried to tap on maf and cracked it.. the idol didnt change... he uses a snap on scanner not sure model or type..
