I thought perhaps this was because of the transmission shifting from 2nd to 1st but i cant say i feel the tranny shifting and it wouldnt really make too much sesnse if you ask me.
I have cleaned the TB, new air filter, and checked the PCV recently and theyre all good to go. I did not replace the PCV but it seemed to function alright. The engine idles at about 5 or 600 when warm and runs great but i just cant for the life of me figure out if this behavior is normal or maybe theres something i need to check. Any ideas? Thanks
