[SSGT Mustang]

When I took the cover off the computer to install the Quarter Horse in my convertible, I noticed that the legs on some capacitors had corroded away. The other components were fine, since the motherboard has a coating on it to cover them. But the legs on the capacitors are exposes to the elements and will corrode over time.

I replaced all of the capacitors. There are electrolytic capacitors and a couple of tantalum capacitors. But, this is not such an easy job. You have to gently remove the coating on both sides of the motherboard to de-solder and re-solder the components without ruining the tracings or the solder pads.

My advice...take a look. If the capacitors are secure and not bulging, then you're probably fine. If not, then you should probably try to repair it before going out and buying a replacement. It's not hard to replace the capacitors, it's just tedious.

Those computers are made to last. They used top of the line components, and protected them with a very durable covering. You're probably fine.

Again, you just got started. Take it one step at a time.

A good way to get a baseline is to replace all of your sensors including the O2's. Clean the connections from the harness to each component, clamp them a little to make them tight and reconnect using dielectric grease. This is especially important for the O2's. There are the connections at each O2 sensor, and then a connection near the passenger strut tower Do them all. Make sure you do the same at the two multi-pin connectors on the upper manifold.

Then, bring it to the track and make one change at a time. Log each pass.
