I recently replace the MAP sensor and hose and it runs good with correct engine idle till it gets up to operating temp and then it shoots up to 3000-3500 rpm’s. However yesterday I let it run and unplugged the egr valve (I think is what it’s called) that goes into like the throttle body and it dropped to like 600 rpm’s while it was unplugged left it unplugged for probably 15 seconds then plugged it back and it idled perfect all day and then this morning I started it and it shot up to 2500 rpm’s and then I tried that process again and it didn’t work. Very confused any help is appreciated
