No, I did not replace the injector seals. I couldn't find them anywhere around here, and had to have the car back up and running asap.

Can you say without a doubt that is most likely the cause of this smell? I guess I could smell a *faint* odor of gas from the IM area, but I just figured it was due to removing the injectors and a bit of gas getting spilled somewhere.

Is it possible there is something else wrong? I mean you can only smell it when the heat is on...
