the computer is going to show you a calculated pulse width based on a bajillion other things, you cannot see through the datastream individual injectors due to TPI cars being batch fire cars. The vehicle needs to be able to reach closed loop in order to make intelligent fuelling corrections, otherwise its operating blindly (no feedback from other sensors and such).
If you smell gas in your oil then it could be a leaking injector, your fuel pump cannot provide enough pressure to have a "spray" so the injectors are dripping when they open, or you are getting little to no spark so the fuel just goes in and washes out the cylinder.
