Spark Plug Wire Replacement

[skorpion317]

A couple weeks ago, '98 Camaro 3.8L developed an intermittent misfire. When a heavy load is placed on the engine (like high-gear, low-speed acceleration, or normal WOT acceleration), the engine misfires a few times before smoothing out. The MIL does not come on at all. If I am cruising (partial throttle) or just doing normal stop-and-go driving, everything seems fine.

From what I understand, this sounds like a bad spark plug wire. I know theses cars have problems due to the asinine location of the spark plugs underneath the exhaust manifolds. As far as I know, the plugs are still fine, it's only the wires that will need to be replaced. Can anyone back me up on this diagnosis?

I have seen a bad coil do the same thing to our cars as well. So it could be a spark plug, wire, or coil possibly.

True, but it's often the simple things that go wrong first.

not always, some water falling off the cowl onto your coils can easily make one fail. Has happened twice now to my brothers car

Hate to sound stupid, but what do engine misfires sound like?

It sounds like the cylinder missed its combustion. like there sould be a sound, but there isnt. once you hear it you know what it is.
