I took my car to the shop to see if they knew what was wrong and they dont evan know where to start. It started idling high but it dosent do it all the time, sometimes it will start when its been running awhile or the other way around, than after that started it started shifting funny,it shifts fine if your foot isnt on the gas but if it is you have to let up off of it fot it to shift, it also has been sucking up gas big time. The shop said that no transmission codes showed up so he dosent think its the trainy,theres also no engin light on either. If anyone has any idea let me know, I would like to get it fixed but dont know where to start cause I dont want to replace something does not need to be replaced.
