Thanks for all the info Steve, I'll check both the socket and the EHA as soon as the car is in the garage long enough for me to get under the air cleaner.
Incidentally, any tricks to removing/disassembling that part? I've noticed that the top half is secured by several clamps, as well as what looks like four locking nuts, which are torqued down pretty hard. Is there anything besides the air filter in there that would necessitate such a secure housing? Also, does the hose running from the air cleaner to the engine cover detach from the air cleaner, the engine, or both?
