Anyone out there with a 4.3 liter, Is the rough idle in my head ?maybethe idle I'm experienceing is normal any comments............

 

I have onwed one truck with a 4.3L and it wasa 93 S-10 4x4. It always had a rough idle no matter what I did. I'm not sure how the new 4.3's do because I have a 5.3, but I do know that Chevy can be notorious for rough idle's. There are some guys on here that have 4.3's so hopefully they can help you out. Good luck

 

My 03 has a rough idle too. But most of the 95 and up gm cars and trucks I have driven have had it. But it is real noticable in the 4.3. I have a 4.8 work van that has it too.
