New to this so bear with me..I own a 2013 F150 3.5...last week it wouldn’t start so pulled the 27 fuse and it looked fine. Cleaned it cuz it was dusty, Popped it back in, turned the truck over and it started with the check engine light and the wrench on but then died once again. Started it again and it seemed fine. Towed it to shop. No Dtcs codes so I had the relocation kit installed..said everything seemed good after that was done. Took it 5 min down the road at about 60Km and I’ve now got an insane amount of vibration driving down the road, but it seems to not be constant. Two hours before the truck first died I had an oil change done..but was told this wasn’t the issue. I’m wondering if thats possible because it starts fine and seems to run well but now why do I have the vibration? I’m lost! Any ideas would be helpful before I take it back into the shop again... thanks!
