You should not be able to adjust the idle speed on a TJ since this is done by the ECM and the idle speed valve. If you adjust the little stop screw under the throttle plate the idle valve should compensate by moving in and out. This valve gets dirty sometimes and may need cleanging?? Just an idea.

Also do you have a speedo cable hooked up to your Dana 300? I think the ECM gives the engine a little bit extra rpms until it senses a stops. Maybe way off but I remember reading something along that line a long time ago.

this all sounds like sense, many thanks! i adjusted the idle by shortening the length of my hand throttle. speedo cable, no, not sure how i'll get round that one as its an early d300 with mechanical speedo cable...

Brake assist check. Engine off - repeatedly press and depress the brake pedal until it is solid then start the engine, pedal should drop slightly and thats it. If it drops to the floor then servo needs overhaul or repair

thanks, presumably with my line lock open?

If you look you will probably find several outfits that make speedo adapter kits for a d300. Its a good chance is your issue. I did a lot of research into the fuel system when I built my stroker and after when I was looking into supercharging it and I seem to remember idle and speed were related.

The front drive shaft uses the same 1310 cv as the standard custom rear shafts so thats an excellent idea.

The tube thickness is the same as the Tom Woods shafts and for an XJ it doesn't need to be cut down

mine is cut down from the TJ front length, bt not as short as a TJ rear as I am now at about 105" wheelbase....i think!
