1997 Jeep Wrangler--stumbling!!

I'm at the end of my rope.. I did a tune up on my jeep.. Plugs, rotor, cap, wires.. When I buttoned it up, it started to stumble and jerk.. This after warming up and not when I steppped on the gas.. it was on level ground, or when I decelerated.. when I put my foot into it, didn't hesitate once.. but lots of hesitation, "stumbling", coughing when I took my foot off the gas.. Weird!! so I decide to change out the coil, Camshaft position sensor (in the distributor for my Wranger) and the Crank shaft position sensor.. Now it runs bad all the time.. stumbles, coughs, hesitates.. Got code 11 three times on my dash when I checked my codes and now the check engine light is on.. Anyone with Jeep knowledge.. PLEASE HELP!!!

Code #11 refers to no crank reference signal detected at PCM.Check all your connections first.You could easily back out the crank sensor and re-install it again.

Well for what it's worth, , ,
I changed my plugs about a month ago @ 65K, result was better gas mileage and smoother running. Just last week got around to the cap & rotor, , about three times a day the Jeep would "cut out" and sputter but kept running and all would be fine again. Checked the part with no visible problems, , replace with the "old" cap & rotor now it runs fine again. Auto zone will be getting these back.

PS. No codes
