Really? Where did you get this little nugget of information? NGK was founded on November 11, 1936. Champion was around for somewhere near 20 years by then, and probably knew how to spell copper... I'm not making any arguments about quality, but Champion has made "copper" plugs from day one. Nobody gave a rat's butt about that until platinum and iridium plugs came about, and marketing departments realized they needed something to crow about to sell the regular ones that have been around since the turn of the last century. NGK certainly did NOT invent the copper plug, they copied the technology just like most other Asian companies have. Bridgestone's founder chose the name because it "sounded like Firestone", which lent his upstart company credence. Fast forward 50 years or so, they bought the poorly run US company out...

Just replaced my track bar, death wobble use to be at 40mph, know its a 50mph. My tires are toe'd out a tad bit, how do i bring them back in, and also could my tires being toe'd out cause death wobble ?

My 98 is still going up to 4k rpms when I start it after doing a head gasket job
Took old intake manifold off it was broken/cracked
Replaced it with a good 97 xj manifold
Replaced iac
Checked all fuses (just incase)

The only advantage to rubber is the added vibration dampening, which everything I've read indicates isn't a noticeable problem with the 4.0L.

I've had that problem twice. Once was after a river crossing when the entire motor went underwater. It did that for a couple hours til it dried. The second time was a vacuum leak. In my case, the MAP line from the throttle body and one of the EGR lines were both loose.

Also ensure your trackbar bolts are properly torqued. Many people fail to do that, myself included, and you don't wanna lose that nut while driving.
