Having some issues with my 99 sonata I thought it might an issue with the pcv or throttle body sensors, but I don't think thats it, I am going to post what the car is doing, and see if anyone has any ideas on what the problem could be....When driving the car, we were stopped, to make a turn, after the turn, we gave it gas, it seemed to jump hard (like being hit from behind) and then go fine, but as soon as you stop or slow down and have to give it gas again, it has no pick up to it. This has happened 3 times in the last week, not only after a turn, but also just driving, stopping at a light, and trying to go again. Does anyone have any ideas on what this could be?
