I have a 2000 Hyundai Elantra, which just started ticking. I am almost positive that it is the lifters, due to low oil. (wife's car lol) I changed the oil, but it still ticks. I have not drove it at all, just started it after adding new oil. I suspect that I just have to drive it for a while for the lifters to stock ticking, am I right? Next problem, this one is my bad. I spilled a bit of oil when adding, so I decided to spray some degreaser on the engine and spray it down with the hose. Well the engine is nice and clean but now my car is not functioning properly. It shakes when I hit the gas. The engine light came on as well. I am sitting here now hoping that if I let the car dry it will work again......any suggestions or solutions other then going to the service station.
