So for the past month I've notice once in awhile when I start the car it idles ruff the needle will jump but settles after a few. This morning on the other hand I started the car and it was a violent idle the whole car started to shake felt like the engine was struggling to stay on and it stalled. After a few attempts still nothing same thing. On the last try I rev'ed it and kept my foot on the throttle to keep it from stalling and she settled. Turned it off and on again and back to normal. The car only has 17k on it and only thing Iv'ed done is add the jbd anyone have similar experiences? Or any ideas what it can be?
