Help me make it to DGRR! Car will not rev...

Hey guys, so I was wanting to know something...

Are the primary injectors supposed to be running at 100% duty cycle when the car is at idle?

I thought that it would run them a lot lower...

also, how many inHg is the MAP sensor supposed to hold? I tried to test it with a vaccum pump and it looks like it wouldnt hold vaccum.

(When I put my finger over the hole, and pumped the vac reading was fine so I know the guage works.

^That's not right. They shouldn't be running more than 80% at redline, let alone at idle.
