Specifically "Check the timing with a timing light"? I don't see where you mentioned that you did that. Replacing random parts hoping to fix the issue is not smart and very expensive.

why don't you adjust and turn your idle screw up on the T/B.

knuxx

yes i do the timing, and the idle screw, if u loose it the idle dont go up, ..

Bleed all the air out of the cooling system.

knuxx

i already do that, but my question is, why the low idle only happen when the engine warm up, if it cold and A/C is turn off it run very nice.. but when it gen warm the low idle appear
