Icon9 Still chugging

Brand new to the forums so here goes.
Over the last few months I have changed the spark plugs, SP wires, serpentine belt, air filter, fuel filter, idler pulley, tensioner pulley and assembly and just recently the camshaft synchro and the sensor on top of it.
I have thoroughly cleaned the mass air flow sensor (with the MAF spray - did not touch it!), throttle body and the Idle air control valve. And those fuel additives to clean the injectors don't help either.
...And she still chugs at low revs - frustrating! She also winds over fast and several times before she fires.
About the only thing left I can think of is the PVC valve, a clunky fuel injector or one of the wires or plugs are bad.
So basically, it is an intermittent starting problem with a misfire at low revs.
Anyone know what this is?
Thanks in advance.
Oh, it's the 3.0l V6 manual Edge.

Went out tonite and when I tried to start her, she wound over and only just caught and fired, and also again when I went to come home. I'm lucky she started. Sounds like a loose plug wire? I'll have to check it out in the morning - too dark and hot under the hood now.

No contributions yet so I have been digging around some more myself while the truck is in the shop - had to do it as I need it for work which I had to miss today.
Anyway, I have found a very likely culprit in the Ignition Control Module.- it could be a bad connection in the wiring underneath one of these relays.
The other culprit could be the ignition coil pack.
I can do the coil, but the wiring connection, if thats what it is, I am better off leaving to the mechs.
Hope this helps someone else experiencing the same annoying problem.

Talking to myself here but I found out the main problem was the coil.
My fuel pump is not in the best of health either but is manageable for the time being.
Might try and get my injectors professionally cleaned and that should help too.
Hope this helps someone else out there.
