I have a 2005 kia sedona minivan. About 5 months ago i went to do a tune up on it and found cylinder bank 4 spark plug engulfed in oil. I have spent $1400 on repairs that im not sure if it did any good. I have changed the vapor canister and purge valve. Firestone has hanged valve cover gasket and the car is still acting like it is either misfiring or wanting to choke out. It only does it in drive while idle. When driving or in neutral or park it does not do it. Need some help here
