Question on satisfactory spark plug cables for 3.5L

[Ed Tee]

I have a rough idle on 96 Intripid with 3.5L and I want to change my spark plug
wires. I checked on prices and found the following:

Napa $50
Autozone Bosh $80 and Double Silicone $60
Belden $55
MoPar $90

I have read here that MoPar cables are problem prone.

Any body have good results with any of these listed.

Thanks, Ed Tee

Have had good luck with AC-Delco wires. Lifetime warranty and around
$40. 50K and no problems. Easy to install. Wipe off the coil pack
terminals with a clean rag and remember to apply the silicone grease to
the inside of the boots at both ends of the cables.

The first generation LH cars with the 3.5L have a tendency to develop
intake manifold gasket leaks which can also present as a rough idle
and/or misfires. Listen for a hissing sound at idle with the the hood
up.

Good idea to also clean the internal surfaces of the throttle body with
solvent and a toothbrush. Buildup at the trailing edge of the butterfly
valve will also cause rough idle. Can be done without removing the
throttle body from the engine. Just remove the flex host at the inlet
side.

I used to fix a "rough idle" on my Intrepid 95/3.5L with $3 fuel injector
cleaner. Works for me. 170k miles on original wires do not have any reason
to replace them yet...

The NAPA (Belden) wires will work fine.

As Mike said, your rough idle is liable to be a vacuum leak
between the lower intake and the cylinder head, usually
cylinder #5.

I've had decent luck with Beldens from NAPA, ROTTEN luck with the crap
Autozone sells, and right now I'm running a set of AC/Delco wires that
look every bit as good as the Beldens.
