Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
just replaced the valve cover gaskets on 2002 Hyandai Sonata. Re-clamped the contections and vac hoses. Car starts, backfires, and doesn't idle. When excelerating, engine runs smooth. Was running fine prior. Will accelerate, but weak, and dies. Puts out unburned fuel out the exhaust. I believe that I put back all of the connections and hoses properly.
I had done the valve cover on the forward 3 and ran the car. All smooth. Did the same with the rear 3 under the intake (marked each as came out, but will go back tonight after work and remove the intake and recheck. It has the plug leads that go through the valve cover. Believe that they are correct. Could it be the three wires that plug in (one lined up with each plug. Smaller with snap on?
will try it. Thanks.
