so i have a hesitation at 1900 rpm i know it has something to do with the electrical system and grounds but has anyone know what certain ground it is?

 

Hesitation as in the car feels like its spluttering as if its starved for fuel? If thats the case try adding a few more grounding points in your engine bay. Off the top of my head I added a cable running from the negative terminal on the battery to the chassis. Using that same chassis point I ran another one to the bolt on the alternator.

Using the grounding point already on the fire wall, I ran another wire around and somewhere close to under the air box.

It cost next to nothing to make these wires up and they work very well. Try doing a search as there are a few pictures of where to ground them.

Also try looking at your spark plugs to see if they aren't dirty. Good luck!

 

i have my battery relocated so how would i make one from my battery to my engine anyone know?also its like a dead spot i will accelerate slowy from a stop sign then once it hiots 1900 rpm it will stop then go again like a buck or somethin like that

 

I'm assuming you relocated it to the boot. As long as it grounds to the chassis somewhere in the boot it should be ok so no you don't have to run a wire all the way to the front.

Here is the guide I followed:

As you can see theres up to 7 ground points. I only used 4 and it solved the problem.
