For a 96, you should have 49 psi, plus or minus 5 psi at the fuel rail.
Good luck and let us know what you find!
I agree. But also are you sure the wires are on the plugs/ distributor like clicked down in place? Also I doubt this very much but maybe the new wires are arcing a crossed. Do you hear a tic tic tic sound when its running? Another thing to maybe the plugs that you put in are just bad plugs. Its rare but ive seen it a few time new plugs either have a crack in porclein from factory, or putting them in cracked the porcline. It really could be a number of things.
