240 with b21ft. if I don't warm it up it will sputter, but when its at operating temp it will drive fine. also when i am sitting at light it will idle a 1500. For example if i turn it off and then go in the store and come back like 10 min later it will idle back at 1000. I'm not sure it I turn it off and then on again it will do the same but It most likely will,. could vacuum leaks do this? this all started happening after doing m46 swap.
edit: im also getting bad gas milage . 14mpg. im usually getting 17/18mpg
