You are probably looking at a fried computer, but before assuming it is, we need more details, what exactly is the car doing. Is the car dumping raw gas? CEL Flashing, any codes, etc...

I have access to a hand held scanner and it just shows "cylinder 2 misfire cylinder 3 misfire running lean "- I don't think it's dumping any fuel - 2 & 3 miss all through driving range- started with #2 then got worse and now 2 & 3 are missing.

You need to pull both of the spark plugs, make sure firing order is correct, you may just need a coil pack. If the plugs are bad, do all of them, makes no sense to do just two.

You should check the injector harness to make sure it isnt cut, burnt or damaged in any way. Also check the connectors to make sure that the pins have not pulled away from the plug.

If you are looking for a 95' V6 wiring harness I have one, PM me if you want to buy it. I also have the ECM for the same car, its a 5spd car.

Also take a look at your fuel pressure, I think it is suppose to be 38.5psi, your manual will say exactly what it is.

Good luck.
