Front end vibration (potential drive train) occurs at electric gas crossover point

When I have my foot on the gas pedal and the power bar is up past the halfway mark say between 52 and 65% right about the point the engine begins power the vehicle if I hold the gas right at that spot it start vibrating and shaking . It’s not smooth at that spot it’s choppy and makes the front end vibrate. If I hit the gas so power bar gets up in the red it goes away then if I let off and then hold the power at that same mark it starts doing it again. Sometimes if I let off and don’t even put my foot back on the gas when the power bar passes back through that spot it will shake a little as well. Had it in for inspection two weeks ago, alignments we’re fine they checked my tie rods etc and everything checked out. Service manager rode with me today and I was able to show him what it was doing. Taking it in tomorrow so mechanic can ride with him.

anyone ever experienced this problem? Know what it is etc

thanks in advance for any help

 

150,000 don’t think I’ve done that. I’ll ask about it tomorrow when I take it. What is it exactly does it do
