Re: 89 S10 4.3 misfire

We have pulled the plugs and none of them stuck out from another. All looked fairly normal. No smoke from the tail pipe. We have changed the plugs and wires a few days ago. We did notice, after starting the truck a few minutes after running, the exhaust smells like raw fuel. The hard misfire is only present at idle, and moving from a stop. The truck can cruse on freeway going 70mph no problem. We have found a good used (Compression tested) engine a county over with 98k miles for $450. Might be way to go
