well my IAC valve was messed up for a while and had a 84 vette crossfire motor kicking around so i pulled the IAC out of it and placed it on mine, started it up and runs better then ever!!! was i ever shocked to see that the 20 year old IAC valve was working fine and that a 93 was able to use a 84 IAC. well i guess GM did soemthing right! or did they?

 

i think the 93 had different IAC type than 94+, not sure on that though

 

well its the same as a 84! and the crossfire motor has two TB's so i got another IAC as a back up

 

I would bet that IAC was not built on a Friday or a Monday. In fact, I prefer not to buy anything built on those two days

 

must have been a wednesday!
