No, we have not actually seen the injector spray gas into the throttle.
The guy that was looking at it seems to think there is too much gas
getting to the engine and flooding it out. The oil has a gas smell to
it.

Also, the timing belt was changed when we were trying to figure out the
problem. The car has 130,000 miles and we did it just for maintenance.

The mechanic that has it now has done all the tests on it and he says that
everything checks out.
