My '97 civic dx hatchback started stalling while idling once it gets hot. The car starts fine and runs ok, but once the engine gets hot, around 15-20 mins driving time, it will stall once I come to a stop. It will crank back up and run fine until the accelerator is depressed, then instead of returning to an idle speed it should, it dips way below that and stalls. I have not found any vacuum leaks and no codes are generated by the ecu. Any ideas? It's a 5sp manual, it that matters, with 296,000 miles.
Thanks, Tom
