I've noticed a peculiar hiccup in the idle of my truck. It does only do it when it is warm or once the cold start injector has kicked off. Here is what happens it will idle smooth, I mean balancing a champagne glass on the valve cover smooth for about a count of 3 seconds and then it gets the slightest hiccup nothing serious just enough to note it in the exhaust tone and when inside the shifter will jiggle along with the idle until the hiccup then the shifter will jolt slightly with the hiccup, thats how I first noticed it. Anyways this goes on and on the same process. I dont know if its just me and I'm expecting a honda accord smooth idle or what but its bugging me. Otherwise no other problems no hesitation, or stumbling while driving, no surging or sputtering. So whos got ideas?? Thanks alot.
