code P0010/ 2016 sonata 2.4
 

So wifes car starting runny funny, idle going up and down, and then chk eng lite came on, Had Autozone check it and they said it was that 0010 code, and i needed to replace the VCT solinoid. So i did, car ran normal for about 20 miles then started same issue again. Had someone else code it and they said i needed to replace the cover assembly over the VVT, did that and car still runs like crap, and now it seems to be in limp mode. Had it coded again, and they said it was 1326 Glow plugs, he said that didnt make any sense because glowplugs are for diesels. After i replaced the cover assmbly, i ran the car for 20 mins then removed it again, and there was some oil in there again. I'm lost now, any suggestions?? Thanks guys
