Anyone know what could be causeing a very slight uneven runing when I first start the car from cold, when the cars warms its Ok no runing issues when warm idles normal when hot. Could the egr valve need cleaning????? Im not sure what. To check first its like from cold the car not getting enough fuel,from cold if I give it more fuel its Ok to its only on idle from cold the problem is.
