You can always up the idle timing a few degrees to raise the idle speed. What do you have for total advance now? These things like to be on the rich side, so perhaps upping the idle mixture a bit will help idle speed too. I use a CO machine and set idle and main at around 6% each. The factory specs are super lean. You could also disable the retard. All it's for is emissions. So, there's 2 things that will raise idle for sure and 1 maybe.

As John Walker said bump up timing at idle.
The timing range for our 2.4's at 6000 rpm is 32 to 38 deg. If I set mine idle at factory spec 5 deg ATDC my advance at 6000 is only 33 deg. I set mine in the middle of TDC and 5deg ATDC line. That 2 1/2 deg bump at idle bumps my total advance to a tad under 36 deg. Much better idle and wakes the car up. I do use 91/93 octane. Or as John said eliminate the vac retard. at 6000 the timing bounces a little so use a good timing light.

Yep, I too run my timing advanced. I'm old school and time by ear/feel, which equates to 35.
