So, my car has been idleing iffy for a while. After i ran some fuel system treatment, and cleaned the IACV, it's still idled too low, but a lot smoother and no longer shakes the car. However, today when starting it something was weird... My car had only been sitting for about 30 mins, so it was still warm. I started it up, and the engine remained running but barely (at what looked like 0 rpms on the gauge). After about 5-10 seconds, it suddenly jumped up to 750-1000 like normal without me giving it any gas. Afterwards, it was still running like normal and the VTEC was strong...

It's been starting iffy all day though, don't know why. Sorry this got a little long, but anyone have any ideas?
BTW: I was not out of gas because i've got over half a tank. It seems as though the engine wasn't getting fuel for a second though

Help Please!!
