Hello, If you open the throttle a little during cranking, your bypassing the iac system, I can't say it is faulty, just a thought. If you floor the pedal, it may cut off the injectors. Can you check fuel pressure? A vacuum leak or sensor problem might cause a surge.
Can you check for codes? Some of the national brand auto stores will check some codes for free, if you can get it down there.
