Thanks for the reply Chris. I actually figured out the problem last night. I took the airfilter off and messed with the kickdown switch cable to see if that was the problem and it turned out that thats all it took. I figured that was the problem because it seemed just like the kickdown switch had been pressed because of the first gear start and everything.
Free first gear start I guess...
Anyway, it might be worth checking out.
