Occasionally, we have A9L computers available for purchase for $575. These are rebuilt in the same manner described above and carry the same warranty. If we have any in stock they will be listed here

The A9L computers were originally used in the 5.0 5-speed cars from 1989-93, but if you are doing a mass air conversion on a 1986-88 you will also need an A9L. We can rebuild any 1988-93 computer, regardless of the designation, A9P, A3M, C3W.

We are not able to diagnose computer issues prior to receiving your computer. If you need assistance determining whether your computer is not functioning properly, we suggest you take it to a qualified professional in your local area.
