At roughly 45 to 50 mph it will push forward quickly then back like a rocking motion front to back The rpm needle is also jumpy during these outbursts. The check engine is on. It idles very roughly, shutting off sometimes and it has relatively normal acceleration charicteristics until about 2500 rpm when it starts to push. I called it surge but I guess thats not exactly correct thank you for asking me to clarify and not ignoring me like other websites namely Neonz.org.
Haha,
so have u pulled the code? That should lead you to the problem. Goto autoZone...they can pull it for free.
Could be anything with misfire OR tps leading the way.
