I have a 1999 oldsmobile 88 with 118,000 miles that I just bought. The trouble code shows a #5 cylinder misfire. Previous owner replaced coil, plugs and wires. I took it to a local garage and they told me # 5 cylinder had 80 pounds of pressure. They put the valve cover off and found no problems. They called me and said they could pull the intake off to check the lifters, etc. But they said to do this would be a few hundred dollars. They also said it could be a piston problem. I didn't have them explore any farther than that, and I picked up the car. My brother says I should just get a used motor. What's your opinion? I can get one used for $400. The noise sounds like top end noise, but at times it makes a noise like a bad harmonic balancer. Thanks for your help.
