If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum.

Hi everyone.

I recently purchased a 2012 rspec sedan with approx 76000 miles on it. It seems to have issues with full throttle acceleration. you can open it wide open and the engine revs but it picks up speed slowly and doesn't pull very hard. back off the throttle slight and it.feels like a turbo kicks on lol.

My first thought is fuel problem under WOT.

Does anyone have any ideas or have any of you experienced this??

Thanks in advance!
