Re: 4.3 vortec V6 running terrible
I had a 90 that used to leave me stranded in intersections when the coil would quit but I got used to carrying a spare and one time got it swapped out before AAA arrived. I think I went through about 4 in close to 400k kms.
I suppose yours would have a different coil setup though.
Have you changed the fuel filter and spark plug wires?
