I have an 04 sprinter and am dealing with a stall concern. Sometimes it will stall in 100 yards and somtimes it takes 50 miles. I can turn the key all the way off and then back on and the van starts and runs fine for a while and then will stall again. It stalled on me 15 times in a 3 mile distance on day. Is there any one that can help me with this concern. I know that this is a fuel injector B circuit code. I need to figure out how to diagnos this code. Is there any pim piont testss out there that I can follow. Any help would be greatly appretiated. Thanks.
