Injector mounting in manifold.

[Ben Swann]

I'm following up on thest questions.

I'm toying with putting a cold start injector in the place where the air
temp sensor is and using the boss in the manifold for the air temp sensor.
It seems that this should work fine, as the boss was used for the temp
sensor on earlier cars.

So questions are:

1)  Will the inlet air temp sensor should work fine if located in the boss
on the manifold just past the throttle body?

2)  Will a cold start injector work fine as a supplementary injector, or
should I procure an alternate injector?  What alternative can be used if
need be - it would be nice to find one that fits the mounting of the CS
injector.

I plan to use 034EFI supplemental controller to fire the injector.
