Guys remember when installing the gaskets use a spray adhesive while the gaskets are laying on some cardboard. Let them tack up then lay then on the motor side of the intake runner. Press down and sit them well. They won't move after that. I've taken mine on and off at least 5 times and no codes for me. This is for the needswings gaskets, not the stock ones.

 

Glens P0505 code was fixed by installing new manifold gaskets so I doubt that the RCM has anything to do with the P0505 code. I believe others also installed new gaskets and the P0505 code never came back.....

 

agreed ,,, and check the Y couplings and clamps, if they are loose you will get the code,

 

That is correct.

 

What I found on my coupe's RCM is the contacts on the relay that controls the air pump are badly burnt. (pic later)
I haven't changed out any gaskets and checked all connections when the code first appeared. I cleared the code and I say a month or so later it reappeared. Thinking perhaps the relay isn't always making good contact thus not turning on the air pump then throwing a code.
One of these days I'll get a burnishing tool and clean the contacts, clear the code and see if it comes back.
Might swap RCM to the roadster and see if the fault follows.
Thoughts?

 

Tighed1, that is what I looked for when I took my RCM apart. Didnt find any burnt contacts. (Still think solid state relays would be better). I did re-solder ALL the connections on it though. I still had the intermittant no start so I swapped between the SSB and the Aero. I still have the intermittant no start on the Aero. RCM ruled out as cause of my issue.

 

I got the P0505 because the manifold screws came loose. New gaskets and a little Loctite Blue and all is well again. No more P0505.
