hopefully that got your attention haha. Anyways I need a little help with my car. recently its started bucking. I am taking it to the dealer to call them up on there warrenty. I just dont want to get ripped off so looking at few other opinions.
description
It happens in overdrive, at 30mph 45 mph and 75mph from what I can tell right now. it jumps 200ish rpms, and happens flat ground or up hill. The shifts are good. have a SES light for p0442 for a small evap leak. when revving in park, engine has no issues at all.
what I've tried
lucas fuel cleaner/mobil premium. seemed to help and get less common but now its happening more frequently. other than that not much cause of the warrenty. I do not want to void it.
What i think it could be
I don't believe its the wires or coil pack they look brand new. I am unsure on the plugs because I have no blinking engine light, and when revving in idle it doesn't have any problems at all. I believe its transmission related. but all I could think of was fluid change, vss sensors, and torque converter(dont know if it is for sure cause at all other speeds it stays in over drive just fine)
addtional info
if im in the bucking and tap brakes it stops rpms jump, drop, then start bucking again. mpg is perfect. Speedo bounces about 5mph
thanks for any info help and patients for reading this. Will appreciate any feed back.
