2004 SE Electra, replaced the screamin eagle air cleaner with a performance machine air cleaner. All was fine for a couple miles, then I went to slow down and the engine would not slow down, had to shut the bike off and had to ride it that way until I got home. The engine was idling around 3000 rpm and it set code p0505. Took the air cleaner off, checked to see if the sealed idle screw might have moved, which it did not, the throttle is closing all the way, the IAC motor traveled out then parked when I shut the ignition off. Cleared the code and started the bike with the air cleaner off, everything worked normally. There is nothing on the backing plate of the air cleaner that can interfere with the throttle linkage or anything like that. Put the air cleaner back on, and it idled very high and set the code again. Took the air cleaner back off, and everything was normal again and the code was gone. I cannot see anything about the air cleaner that would cause the bike to do this, but I'm obviously missing something. Any thoughts would be appreciated.
