It would be cold by the time they delivered it from Utah to Arizona. I could put it in the microwave, I guess.

I'm guessing the sync generator in your dizzy has failed since your Jeep ran okay with the injector wires mixed up. Might be time for a rebuilt one.

Little Ball, Long Green, Tee Your White Ball. Hey! Wheres the love? I thought that was clever!

I just checked LG & B. (2&6). Only needed to check two as if the front pair are correct, and the rear pair are correct, 3&4 don't cross easily. A real bear on mine to get AT the color code under the boot. All's good, thanks again. Yea, Seth, I like the "advanced search" feature with google. if you put "cherokeeforum" in "with all these words", you get more results from here.

Funny you mention the garage. Just finishing the final touches!

Is the 1-6 in order front to back, or back to front? Do they fire in the same order?

Front to back, and they fire with the firing order, 153624. And btw, I misplaced a firing pin for an old .22. If anyone sees it in the pic, please let me know.

Alright so I've got the plugs right. I was trying to do the injector swap and grabbed the wrong ones. I put the stock injectors back in and now it's running rough, spitting blue smoke, and the RPMs will drop until it dies unless I keep the gas on a little bit. What else could I have screwed up doing this?

Maybe you bumped the MAP tube?>>

There is a brittle little tube. It comes out of a rubber plug, low on the engine side of the throttle body. It runs back to the firewall, then up to your MAP sensor sort of high up there near center on the firewall. CRUCIAL!! The MAP will tell the ECU to dump fuel with less/no vacuum. Any crack or blockage and it will be pig-rich. (black smoke, fouled black plugs). You can pull the line off the MAP and feel for vacuum with your finger. If it runs!

Is that the one back by the 2 injectors closest to the windshield? I noticed that set of tubes kept coming apart and looked about as old and corrupted as Satan...
