Sounds like my recent problem. The car bounced and surged and bucked like a horse at stoplights. The rpm needle would bounce. Accelerating in the slightest would release the problem-no problems while driving short or long distances The longer it went on the worse it got till eventually the car would stall if the red light was too long. Shifting into park at every red light and revving got old. I took it to repair 2wks ago. I had a hose that was cut, possibly during the previous structural repair of springs struts rods etc. They replaced the hose and all is good again. Total bill guessing just under $200 (I had other repairs done on windshield washer reservoir and an air sensor fix I didnt ask for-go figure, the light went back on a wk later.)
