A bad ground will do it as well. I had a loose ground on the back of the driver's side cylinder head, which was causing the driver's back injectors to cut in/out, causing a stumbling idle, etc. That took forever to troubleshoot, and that ground bolt is nearly impossible to get too...and once you feel it, it's hard to tell if that ring connector is "loose"
