I think I would give it another tank before I started taking it apart. Might look and make sure every thing is tight on your air intake and filter. a loose air bridge clamp will some times cause that.Hello,
I noticed my 98 vert idling a little rough this week.
I noticed it after I filled up with Shell Premium last week.
I added some Lucas fuel treatment, but it still does it.
I have a little less than half a tank of that gas left.
It doesn't do it all the time... I will be driving and come to a stop sign or light and it feels like it might die (it never has) if I don't give it a little gas. Or sometimes it is normal.
I am getting no errors or messages on the DIC
Can bad gas cause this?
