I have replaced the egr valve sensor, map sensor, throttle position sensor, feul filter, o2 sensor, and idle control unit (idle air control). Engine still idles up, then down to stalling, then back up, but eventually stalls. When excelerator is depressed the engine stalls. Throttle body injection 5.0, getting gas as well as spark.
