Thread: slite studder when cold start and rev

this is with autolite 104s if u notice in the video it only does it couple times then snappes out of this it happens everytime i first start my car when car is cold i do couple revs then its fine any suggestions they was gapped at .060 but it would do that start just at beging ov rev now there gaped at .050 and it will do it then go away

i had a vacum leak fixed it now its fine and if u watch the video the first couple of revs it studders or missfires then is fine

Mine used to do that, with new vac lines the issue went away
