Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake..

My 2007 Chevy Silverado was starting to almost seem like it was misfiring but I knew it wasn’t rough enough to be a misfire so I put my foot into it when it started to act up and boom I got an engine code and my truck went into limp mode so I was pretty confident what it was after an associate came out and used the scanner tool to read my engine code and boom part was in stock and I was back on the road!.
