Hello, My jeep recently had an error code saying intake manifold runner stuck. I took to mechanic and they reset the check engine light and said call if the light comes back on. it's been about a week and hasn't came on. However, my jeep has done this for a while and jolts randomly when accelerating like almost a kick feeling. I also notice sometimes when getting on the highway and speeding up the RPMs just stay high unless i let off the gas. any thoughts on this whole situation and if it's of urgent concern?
