I have a 93 Dakota v6 auto when I start it in the mornig it sounds like it has a miss and idles funny, I can give it gas at idle and you can feel the miss. I just bout truck and they have replased plugs ,wires ,cape and rotor i just noticed that my 2 bolts in the center of manifold are broken off ,would that cause my problem . I check for code no engine light on i had a 1255 code . Thanks

 

Yes those 2 broken bolts could be causing a major vacuum leak that is causing your problems. I would completely replace both intake gaskets (Plenum and runners). And see if you can remove the broken bolts or just replace the heads.

 

Thanks thats what i thout.I guess heating the remaining 2 bolts and the 2 broken studs would be my best bet on the removel, maybe a small hand held torch thats all I have.
