Car stalls sometimes while idling at stop light and just today stalled while driving, but did not die. Ran rough for a couple of seconds then cleared up, then ran fine for rest of 20 mile trip. Have replaced fuel filter, fuel regulator, TPS, IAC Valve, cleaned carbon build up in throttle body, cleaned MAF sensor. Tested fuel presure with guage while running 47 -55psi stalled with gauge attached and never lost pressure so its not the fuel pump. When i connect the obd2 scan tool live test all looks good, no codes. Anybody got any ideas?? Been working on bow ties for 35 years this ones got me stumped.
