OK i had to take my intake off and when I reinstalled it I now have a speedo that waves at me or just plays dead ALL the time...as soon as the motor is started this happens....All that I changed one that one ground on the motor...it was grounded to the water coolant cross over(hehe I had that off) and it was under the stud, well the stud had a nut on top that wasnt being used so i moved it to that nut and its tight and clean, but now ive got this speedo issue....Im gonna try adding grounds and cleaning all the grounds to see if it helps, but is their something specific to look at to correct this?? It would periodically do this wave deal and then straighten up before...Mainly it was when the cruise was on that it did it but now it does it ALL the time....Any help is appreciated!!! I GOTTA know how fast im driving...I cant do 55 through town(thats the only speed i know im going cause i know 55 is about 1900rpms in OD)...
 
FIXED IT!!!!! I was tracking ALL the ground down back in the area of the engine valley and found one that was lose!!! Back of the head on the left where the coolant block off plates are, the one bolt was half out and turned out it was the ground apparently for the speedo stuff!!! tightened it and so far no waving speedo or it playing dead!!!!!! gonna drive it some and see what it does!!!!
