    Hesitation

    Got a 89 sunbird with a 4.3 omc. When it's in neutral and shift it in to forward,it shifts fine, then when it goes from idle to lil gas it stutters a lil bit then clears up and goes. But when I bring it back to idle then give it gas it doesn't stutter. Only when I go from neutral to forward...

    Low idle

    I think my 1985 4.3 cobra omc has a low idle. What is it suppose to idle at? When I start it it seems a little low,and when I but it in gear it gets kinda rough but when I give it I'll gas it's fine. It's little below 1000,maybe like 700-800 rpm, Sound right? Thanks
