i started running my rs4 3 18ss today for the first time. when running for a good 5 minutes not using full throttle the engine shut off and ever since ive had a hard time starting it back up! there was also alot of oil that was seaping from the engine abit and i dont know if thats the cause of the problem. I tried taking out the glow plug to see if the engine was flooded and some oil was coming out from the side of the engine where the exhaust pipe gets connected to. its turned on but would then die out on me again. any help would be appreciated!
