My daughter bought a used 96 Blazer that had an engine swap. The idle control valve needs replacing and I am not sure what engine is in the truck. The 96 blazer stock item is different that what is in the truck.. The only numbers I have found on the part itself is 2 lines.

96309
85462

I cannot find any reference info for this part. Any ideas out there? The local auto parts stores needs an engine idenity and I do not have one.

Thank you in advance everyone.

 

Take a picture of the intake manifold and post it up. That will help us identify the year of the fuel injection system.
