What am i missing?? Is there a "trick" to popping that sucker free?
Thanks in advance,
It'* hard because it is too simple to believe. After you get the footcover off under the dash, the PCM is clipped onto the plastic frame on the footwall. the clips are part of the frame. Lay under it and look around as to what clips are holding. I forget if there are one on each side and maybe one in the middle. it takes no force to pry them back, so you can slide the PCM down and out from the frame.
Even putting it up is easy. You just start it from underneath, sliding it up in the guides of the tray. There are clips on the frame at the top which you can't see. They will catch, and then you slide and snap it into the frame.
I am on my 3rd PCM for the '95. The first two were preceded by many hours of trying to fix a problem existing only in the mind of the computer. The last one, I got a camshift position sensor error. This is a favorite of the '95, and a really bad one because the message actually means there is something wrong somewhere in your entire ignition circuit. Put in a fresh PCM, and the DTC code was gone, never to return.
So you have to have two pCMs at a time. One in play and one as backup. (I get them for $20/pc at the pull-it yard). If i get an odd message, the first thing I do is put in the new computer.
There is a blue e-Prom inside the boxes. Be sure to swap in your original one. That has your id number. In my state, you can't pass inspection if your car has one VIN# and the computer has another.
