i got a 1995 hyundai elantra..its manual and when its just parked in neutral idleing..after about 3 minutes of normal idleing..it begins to jerk and the car kind of shakes and it almost stalls but then wakes up again...it does this about 5 times...then it goes back to normal idleing ....5 minutes later it doest the same again..i wanted to get a cold air intake for it just for fun and i thaught it would fix the problem.because the stock intake is all old so i dont know if thats the problem... anyone got anything?? thanks...
