219,000km New Plugs and just cleaned throttle body and MAF. when accelerating the car pulsates through the automatic transmision and this week i had a p 0420 code so i pulled my positive to clear the ecm and then it started idling at 300 rpm and shaking. at this time i drove the car on a trip until the engine light came back on then shut the car off. the car was normal again. Recall? on ECM?
