92 olds 88 stalling

[dawn terrill]

just purchased, stalls when in idle for 10-15 mins, replaced o2 sensor and throttle position sensor, still acting up, not only after idling but also when driving. replace electronic control module and disconnect lock up converter on trans have been suggested. any ideas would be helpful since my mechanic is somewhat stumped. thanks

did your mechanic run the scanner across? since some scanners will actually diagnose the engine for yah at least mine does and it's a cheapy from pepboys
