99 Venture Stuttering

FYI - This is for your information since I found the problem.

I recently gave my van a tune-up, including the plugs and wires. After completion it would run fine when cold but after a few miles would start to stutter, almost die when driving. Also, if it stuttered while in a turn it would die, shove it in neatral and it would start right up. After reading some posts I thought it must be the wire connections so I checked the front three (2, 4 & 6), no change. I checked all of the coil pack harness connections and everything seemed ok. So, I had to go to the back three (1, 3 & 5), I rotated the engine and checked the wires, again no problems, pulled them off 'pop' and pushed them back on 'click'. Then I saw the two vacuum line connections located just behind and below the coil pack deck. I had removed the CP deck and the black vacuum thingy :confused: (I don't know what its called) to get better access to the back plugs and I thought I had put them back on correctly:banghead: . It turns out I didn't, I had reveresed the two vacuum hoses and after putting them on correctly the engine would run just fine, no stuttering anymore.
