Intake runner with small extra tube was mistakingly but on left side will this make it run like crap? Just put new injectors in and it ran ok before now i noticed that as soon as i started it it ran awful, then i noticed runner was on wrong side.. There is no difference in them other than the extra small tube. Do i need to switch? Is that the problem?

Extra tube goes on the driver side. The 9th cold start injector. Hard to find replacement injectors or seals for this part.
