My wife's 98 Bravada 4.3L delvelopes a engine misfire during rainy weather. I figure it needs new plug wires. Anyone else have an opinion?

Thanks!

 

Might want to replace the distributor cap and rotor and make sure there's no moisture getting inside it. Check all the ignition wire connections, too.

 

If you changed the plugs recently and reused the wires did you put boot lube or whatever you find it called on the plugs. If not the stock boot lube in the wires is probably non-existant now and might be allowing mostiure to enter the plug wire.
