Engine/ Transmission trouble....

Vacuum would be high idle(or surging) though, not low chugging.

That's not true.

A bad dashpot or faulty air boost valve can both cause dying at idle.

I thought DAs only had those, or no?

Hmm I thought all LS motors did?

I'm also assuming that the car shifts perfectly when driving and there is no hesitation or jerkiness.

What RPM does it idle at in park?

The idle is around 700 and 900 rpm in park....

So it bounces around? What about in drive?

Shh shh shh. Don't fight the wisdom. Just let it happen.

My bad it idled in park at 1000-1100 rpm and in drive it ideal 700-900 rpm

It has to be just DAs, all the intake manifolds I've seen it on have PGM-FI on them. B18b1 intake manifolds don't have that.

You are considering 700-900 as low idle? Because thats actually spot on.

What were you doing before this happened?

I'm a little lost here, does this "chug" happen all the time in drive while you are stopped with your foot on the brake, or in drive as you are taking off.

 

[ImportRacer209]

I was doing 80 or 90 on the freeway and when I took the exit and came to the stop it started chugging and now it chugs when I stop and taking off....

And also m gas is being burned up a lot quicker to

Check Engine Light?

 

[ImportRacer209]

No CEL but my maintenance required light just came on

Were you beating on it?
