Message	I've been having a stalling problem at speed, if I accelerate and let off the gas quickly, the engine will stall as I'm coasting down. Here's what I did to fix this: - Tightened the BOV springs - I installed shields around the dual pop filters - I did a boost leak test, after fixing a big vacuum leak, everything checked out fine. - Ran ECU codes, 55. And I STILL have the stalling problem. Could the MAF issue you described be the culprit, even though there are no error codes?
