Hi I have some kinda vibration in my truck I thought it was a miss in it but when you take off in it there seems to be a vibration for a few seconds then it stops and runs fine it only does it when your taking off in it and you can feel it when it stops doing it because it really smooths out and runs great with lots of power

Yes it can it can be felt in both its very strange lol it only does it for a few seconds then you can feel it smoothout I thought it was a miss becouse one of the spark plug boots had a small tear in it and the spark was coming threw it and firing off of the exhaust manifold so I put some electrical tape around it and it ran fine then a few days later it startet this vibrating/miss thing its doing but I kinda figured if it was a miss it would do it all the time and not just a few seconds when taking off thank you

Its kind of hard to figure it out without seeing the vehicle. Is the check engine light on?

You may want to have it looked at. Its hard to pin point vibrations without actually being able to test drive the vehicle myself, you may want to try and better understand the type of vibration your feeling, check your engine mounts, u-joints.
