I HAVE '05 RAM WITH 5.7 HEMI. AT AROUND 1400 RPM THE ENGINE SURGES AS IF I WERE LIGHTLY PUMPING THE GAS PEDAL. ALSO AFTER SITTING FOR A COUPLE HOURS, WHEN I JUMP BACK IN IT IT STARTS AND IDLES FINE, BUT WHEN I PUT IN GEAR AND HIT GAS PEDAL IT WILL STALL MOMENTARILY BUT NOT QUIT COMPLETELY. ANYONE ELSE HAVE THIS PROBLEM? BEEN BACK TO DEALER WHERE I BOUGHT IT 4 TIMES NOW AND THEY CAN'T FIND THE PROBLEM. NO CODES ON COMPUTER. THEY JUST REPLACED THE MAP SENSOR BUT THAT MADE IT WORSE. ANY HELP WOULD BE APPRECIATED.

 

check the throttle position sensor and idle air control? My truck had a similar problem. I've got the 5.9 360. I think my problem was a loose wire on the iac but I was also playing the the tps and map sensors also. All I know is whatever I did stopped it from happening.
