stubbling when i take off cold
 

when cold around 15-30 its bogs down then jumps up and goes then repeats it just happens for about 5 min.

also my rpms and mph cut on and off when they want to. i have to tap on them to come on some times

how can i fix this

thanks

if you have to tap on them to work then thats were your problem is.

Sounds like a bad connection..

So is it a loose wire or ground? How hard would it be to find the wire or ground?
