i have a very annoying problem and i cant figure out what it is
when my car is running i will get a slight dim that is repettitive
the inerior lights headlights fuel pump and everything that is electrical
pulses. i know my fuel pump is doing it because my fp guage drops about two psi an rises again. it is now getting so bad that it is causing my idle to drop
about 100 rpm. also my air/fuel ratio guage blanks out every once and a while
it will go from a stoich reading and suddenly shift all the way to the extreme of the rich side and their is no strobing effect like there was when i first put it in

i appreciate any help you guys can give because it is driving me insane

also i have had my alternator tested and it is fine

 

does anybody have any help for me

 

sounds like you either got a loose ground wire somewhere or a short in the wiring harness. check ALL connectings.

 

i have checked all of my grounds but i havn't checked my wiring harness

do you think i would need to check my underdash harness also
