I Have A Chirping Sound Coming From My Steering Wheel.
Sounds Like A Mouse Where The Air Bag Is . Any Ideas?

Also On My 2001 Aurora I Just Had A Bad Plug And A Coil
Pack Replaced To Fix A Rough Idle Pproblem. It Didn't Work.
I Pushed My Accelerator Pedal Down Hard While In Park
Just To See What Would Happen And At 4000 Rpm's The Car
Seems To Misfire Or Something. Any Ideas On What Could Be My Problem?

The Car Is A Beauty But I Don't Think It S/b Idling Funny At
30,000 Miles.

Any Help Would Be Greatly Appreciated.

D-Con?

Seriously, I think there was a thread not too long ago about some bearing track in the steering column. I think they were talking about the electrical connections while turning the wheel to start with. A little searching might turn up something useful.

On your bad plug problem:

I went through almost two sets of plugs on my '98 Aurora, one full set, then various plugs on different cylinders over a period of about 1000 miles (luckily I did not have to pay for all of them). The dealer indicated things like "carbon trail" and "cracked plugs" causing the problem. The dealer then replaced the plug wires and the problem went away immediately. I have never heard of plug wires damaging the actual plugs before, but that seemed to be the problem.

Hope it helps.

If the plug wires are not working right it most certainly can ruin the plugs in short order. Jacobs electric makes racing ignition systems. If you search for them, they have loads of reviews of every conceivable spark plug, plus some great explanations of why ignition systems work, and have problems. One of which that jumps to mind is how higher compression engines have to work extra hard to make the ionization trail to form the spark since fuel/air mix is even less conductive than air, and there is much greater turbulence to disrupt it's formation- sort of like blowing out the spark before it gets going.

There are a lot of reasons in their information that makes it clearer why our 4.0s are very sensitive to ignition troubles. I don't really know if that's where your trouble is, but if you do it yourself, it's not too bad of a repair bill to replace the plugs and wires to be sure. I'd have definitely done that before suspecting a bad coil. Damn dealership tried that crap with me. You can imagine their estimate.

P.S. The consesnsus for the most part is use the AC Delco plugs and wires reommended or you'll likely come to regret it. To be fair there were a few poeple of late saying they were thus far happy with some borg-warner select wires I think, but I definitely have had no troubles with my Delcos (that fixed a worsening misfire issue).

AC Delco is what I have in my car after my misfire fiasco. Again, no problems since they replaced the plug wires.
