WHATS WRONG???

[marcus_3050]

Yesterday my car started sputtering really bad at a stop sign and occassionally feal a slight power loss on hills. Check Engine light came on and the code said CYLINDER 5 misfire. I was told it was either plug, wire or coil pack? bosch plugs and new wires as of last July. Which one is cylinder five?

any ideas???

Are the wires resting on the intake manifold?
If so, here's my remedy: http://www.fbody.com/tech/details.cgi?id=53
The one BIG problem among 95+ 3.8 f-bods is that the spark plug wires either rest on, or are WAY too close to the intake manifold. They get hot, melt, arc, then misfire. I had my car in the GM Shop three times in 6 months before I figured out what was happening.
Hopefully this helps.

Cylinder #5 is on the driver side, all the way to the rear(closest to the firewall)

Check your plug wires with a ohm meter!
