My 2002 Seville SLS at 96K miles has started stalling when accelerating from idle (while at a stop light or stop sign). When I press on the gas peddle it jerks and lurches for a few seconds or it outright stalls all together (sometimes it does both - lurching and then stalling). The car starts without a problem. The car does not stall while I am driving, only when I accelerate from an idle while at a stop light or stop sign. I've read that this could be related to an Exhaust Gas Recirculation Valve. I've also read that it could be the IAC valve. Because it does not happen while I am driving at a steady speed, I read that it would not be the crank position sensor. The only current code the car throws is a MSM B2375, which is a stability sensor code (I think). Advice greatly appreciated! Thanks in advance
