idk but is it normal this model car to be quick and nimble when the engine is cool to cold but at optmal temp its slow and sluggish[ like i floor it and it cant get outta its own way] but as soon as it hits like 3500 rpm in frist gear [ could this be with the related problem] its like a diffrent car and im zooming!
