My car will run good on the highway until I get somewhere and it's sitting idling. It'll start running rough and stall out. Sometimes it'll start right back up sometimes I have to let the car sit for awhile. I've replaced o2 sensor, throttle position sensor and idle air control valve fuel filter still doing same thing I'm stumped! I do a driving mail route it'll start out good then about an hour into the route it starts stalling out. Help.

So how is it running now? Same problem for us, but first replaced throttle position sensor and was told O2 sensor bad too, replaced O2 sensor but car was "coughing" more with new O2 sensor, took out new and put back old and problem even worse, haven't tried idle air control or crank shaft sensor yet. Let me know. Thanks
