I have an odd thing happening with the K5. The truck starts, runs, and drives like a champ. The only issue I'm having right now is that my idle is too low in gear while stopped at a light. Out of gear, the idle is fine. If I take her out of gear while stopped, it bumps up to where it should be. The second I put her back into gear, it drops too low again. When I go to accelerate when the light turns green, there is no bogging or hesitation.... My choke is adjusted properly. The timing was bang on last I checked. I'm not running rich or lean, either. And as far as I can tell, I have no vacuum leaks anywhere. Of course, a vacuum leak should cause idling issues in park, too. Does anyone have any ideas?
