2.6L rough idle - Pirate4x4.Com : 4x4 and Off-Road Forum

I need help. My isuzu, which i love, is having a idle problem. It idles fine at normal operating temp. and it idles at its normal high idle when cold, but in between sucks. When it is at a luk-warm temp, it will not idle at all, really. I have tried many things including temp sensor, O2 sensor new plugs and wires, re-set valve lash, etc...
I rebuilt the engine 1 year ago approx. and it has been this way the whole time.
anyone with suggestions would be greatly appreciatted!

my gfs 93 with 2.6 idled kinda shitty and didnt accelerate too smooth, so i put a new air filter in it and then cleaned out the throttle body. runs pretty smooth now but damn her TB was dirty
