My jeep idles at 6*ATDC

I can set the timing, and it will run good, but when it idles it will kick down to 6*ATDC, I rev it,it will jump to 9*BTDC and idle there (1500RPM)and will sound good. It will advance gradually after that, when I rev it.
But it will kick down to 6*ATDC(650RPM), I am really scared to run it like this!!
I is annoying to because it will idle at 1500RPM sometimes, and ping like a bugger, and other times it will Idle at 650RPM and is killin my motor!
What could in fluence the timing like that if the computer is bypassed, the timing chain and gear is ok and it doesn't matter if the vacuum advance is used??
Any suggestion or question would be great!
KEEP ON JEEPIN!

If you have the 4.2, you need to set the timing to 9' with the engine reved to about 1200-1500 and make sure your vacuum advance hose is disconnected and plugged. When the Jeep is idling at its normal 650rpm, the timing will drop.

Re: My jeep idles at 6*ATDC

I did that, the timing was too high, so I corrected it.
But when I went to lower the idle, the timing droped to 6*ATDC!
The odd thin is that it will sometimes stay at the Ideal timing, and other times it has the very low timing!
So I tried to increace the LOW timing to atleast 2*BTDC, it was still crap, because in fifth gear on the highway it would ping like a bugger. I bypassed the computer, so there is no way that is screwin it up!
I orderd a new distributor, but it costs 130$can.
so I am going to hook up my external HEI coil to the ford cap. Check out my other post.
Thanks though, I glad atleast 1 person would give an suggestion.
KEEP ON JEEPIN!
