I'd have to agree with hackish, he needs more vehicles to do testing on. His car is almost 20 years old. There have been tons of innovations since then and a lot of them have to do with emissions. My Paseo which is a 97 also goes into closed loop almost immediately after bump starting. That ensures that the engine is burning cleanly, but it doesn't make sure that the CAT is up to temp and doing its thing. Unless he does testing on more modern vehicles, I couldn't make a decision one way or the other.
