It started early on after getting the car, when my Kia Sportage is driven for a while (more than 30 or 40 minutes) in very hot weather (with or without the AC) in stop and go traffic or if it is hot enough even continuous driving on highway the car starts to run rough. If I accelerate from a stop light or have slowed down and then try to accelerate again it hesitates, shudders, lurches and occasionally when it is super hot out (I live in southern AZ so anything about 103 or so) it won't accelerate and the engine wont respond to the accelerator and if it does eventually respond then as the engine revs it takes a few seconds for the transmission to kick in and get the car going. The obvious answer is to stop driving the car when it is so hot out :) but aside from that. Oh yeah, just had new plugs, wires and a mass air flow sensor changed out but it still does it.
have the same problem?
