Re: CJDave - Decelerator valve/shift on the fly

Hey Doug,
I think dorfs and CJ Dave are giving you good advice on the decel valve/air injection thing. If you remove it and allow some raw fuel into the exhaust manifold you could backfire and the raw fuel will do your cat convertor damage.
I think it would be a bad idea to put manifold vacuum to the axle shift servo, too, because the high manifold vacuum generated during slow speed might do damage to the servo diaphram. There is vacuum to the front axle servo in both 2wd and 4wd mode in order to keep the shift collar in the desired position.

Good Luck!! [img]/wwwthreads_images/icons/smile.gif[/img]
