My car is idling very low, practically at zero.
When I put the car in neutral it stalls or if I push the clutch in for too long it stalls.
I installed an alarm in my car two days ago could some of the wiring have caused this, or is this just coincidence.
I have no CEL on.

 

Don't really see how installing a alarm could affect it unless you really messed up wiring that you weren't suppose to be messing with lol.

Adjust your idle and see..

 

I tapped all the right wires.
How do I adjust my idle? lol

 

I have the same problem but its only happened after I installed my sub. I think its because my voltage is dropping too much because sometimes if I turn the volume all the way down when I'm at an intersection, my idle will go about 50 rpm higher

 

Yeah.
The alarm I installed was on for like 3 hours last night before I finally disconnected it.
I think that might be it.

 

My battery is horrible so I'm guessing that's what could be part of it too.
