Can someone tell me what these connectors do. I did the zoom zoom engine clean today and forgot to plug them back in after I went for a drive. The car wouldn't hold idle but I managed to drive it for about 5 miles by giving it gas right after starting the engine. I finally remembered that I didn't plug those plugs in. After plugging them in, the car held idle. I'm wondering if I did any damage to the engine.

 

*sigh*

It doesnt matter, those are just secondary air injection pump stuff. U can even leave it alone and it wouldn't matter ONE bit

Reason why your car wont hold idle is Your ECU is re-learning the air volume.

 

The one on the left, as NY says, is air injection - but the one on the right, IIRC, is the barometric pressure sensor, and quite important for mixture calculations.

Yeah, but shouldn't hurt the car if run without for a liitle while.
Now since plugged back in, everything will re-calibrate after a drive cycle or two right?

 

Everything should be done in 3 "complete" drive cycle.
