Jumpy Tachometer (video) help

My car had some problems with it stalling out after about 30 seconds of it running/driving. I cleaned out the tb, iacv and the fitv. After no luck, my buddy who is a honda tech came over and told me I most likely need a new ignition switch. He ordered the part and put it in without any problems. Now, after about 10 or so minutes of driving, the tach jumps ahead 2-5k higher than the actual engine speed. It doesn't do this every time I drive the car, and the engine seems to be running fine when the tach is jumpy. The car is throwing a CEL and i'll get down to autozone to get the code pulled if my buddy can't come down in the next couple days to pull it himself. Do you guys have any idea what might cause a jumpy tach? Thanks in advance

Re: Jumpy Tachometer (video) help

i cant see the video at work but im sure its your distributor. the rpm reading comes from your distributor. some times when the dizzy is going bad you will see jumpy rpm needle without the engine really reving up that high
