Vaccum Check Results (First Post!!)

Whats up org Members,
Ive had the engine hiccup problem for a while now so i decided to test all ign. coil resistances. Two were bad so I replaced them. The engine still misses at idle so I did a vaccunm check by T'ing into the charcoal vaccum line,(see pic below). I got a reading of about 21 in-Hg which is good according to the Haynes manual. What do I check next? By the way I also cleaned my TB.

Check your Engine Coolant Temp Sensor. If it is malfunctioning, it can cause a rough idle.

Thanks,
I'll try that and maybe change the plugs too. If all else fails, I'll start looking for a 2k2 6spd
