Well i posted on here several times and no one has seemed to have the solution to my probelm here. My problem is when im around 65+ and let off the gas i get a shaking or shuddering. It only happens when i let off the gas it does not happen when i am on the gas. The engine doesnt sound like it shutting down or anything. So idk what the hell it could be. I was thinking it was starving for fuel maybe? idk Im hoping someone can help with this...

How bad is the shake? is it like a dropped a cylinder shake or subtle like a vibration? I would doubt it is a fuel starving issue since it is doing it on deceleration and not acceleration. When you get off the gas, are you on it doing 2500rpm then you just completely let off like coming to a stop?

When is the last time you did a tune up? It doesn't sound like a major issue, so possibly maybe just something a tune up could fix maybe. Ever tried a system cleaner like seafoam?

The motor was built only a year ago with new plugs/wires the whole shibang. Its basically more than a vibration but less than a dropped cylinder. I dont let off and come to a stop it happens when im crusing in 5th on the highway and let off just to slow down a little and thats when it shakes.
