I have a 94 integra gsr, for some reason my signal voltage is all over the place, i have a good ground, my 5v reference is right at 4.98v but m signal voltage, which is supose to be KEY ON ENGINE OFF is supose to be at 1.6v with my 3bar GM map sensor..Well its not.

I am getting funky readings straight from the engine harness wire itself, like 4v, then .11v then sometimes i will get 1.68 but it dosnt last long..

PLEASE HELP, this **** is pissing me off, i went though all my wires i have no breaks in my harness idk what is wrong.. if I try to start car it sputters and stalls, then i can tell its throwing tuns of fuel at it because i can smell it.

 

Tomarrow i am going to wire the original sensor back up and see if it runs..if so that means i have a faulty gm 3bar map sensor, but i realllyyyy dont think that is the case.. I think its something else..

I also checked all the fuses under the hood, all are good.
