Code 32 - What is this cracked rubber piece? (Page 1/1)

Hey All!

Been almost 10 years since I sold my 4.9 swap and finally got another fiero! Got a great price, but with great prices come lots of troubleshooting/repair. Currently sorting out my code 32. I have this rubber piece here and was wondering if this could cause a code 32, and if others have just connected the hoses a different way it or is it something that can be found/bought? I'm following buddycraig's post on code 32's but figured I'd start with the vacuum hoses first and this is the only part that looks bad.

IIRC it's an "adapter" or "coupler" that connects two sections of vacuum hose to each other. My guess is that it's some assembly line thing to make building or installing the engines easier or more uniform, or possible to keep vacuum hoses positioned in a particular way. It has no actual function... you can replace it in whatever creative way you like.

That does indeed look like the lines going to the EGR *solenoid* (not the EGR *valve*, which is the cone-shaped thing on the other side of the engine on the exhaust.)

The solenoid has a number of vacuum connections of a variety of sizes, and yeah, anything broken there can give you a code 32. Clean it up carefully, like don't break the solenoid as they are expensive to replace, but you may end up using multiple sizes of vacuum hose with junctions from size X to size Y. Dorman sells those little "Help!" packs of tees and junctions for this very purpose.

One of those hoses goes to the cruise control dashpot and the other to the evap canister. They are different sizes to help in connecting them properly.

Your problem is likely the EGR solenoid, a cylindrical object located horizontally just below the thermostat housing neck, the EGR valve itself, located near the ignition coil, the EGR tube, connecting the EGR valve to the underside of the intake manifold, or the vacuum line running from the EGR valve over to the EGR solenoid. The other line coming off the solenoid runs back underneath the intake and connects to the underside of the throttle body. If your emissions decal is still on the deck lid, you can trace these.

You might look at the small vacuum L shaped line loop on the EGR solenoid. The rubber sleeve on one end is prone to rot. You can replace the complete line with a small piece of vinyl aquarium tubing. There is a rubber hose that fits on the nipple on the forward end of the solenoid that connects to a small metal line on the front firewall. That runs to the intake air filter canister, but wouldn't set a code 32.

If Idle is normal, I would check the lines between the EGR valve and solenoid, and the line on the solenoid, plus checking the valve and solenoid for function.

Awesome advice everyone thank you. For anyone seeing this, I removed the black connector bit and the right hose slid right on to where it was supposed to go one I removed the plastic connector. The left one is a different size but the plastic line cracked while removing so now I'm going to replace the whole line. Hopefully this resolves my code 32 if not ill continue troubleshooting.
