Does the ECU report any fault codes? If the actuator and plumbing are OK it looks like the electrical feed to the actuator - but it would raise a code if the ECU was seeing open / short circuit from its' end  :-/

Kevin



Codes 73 and 74 are stored. Both are Maf voltage out of tolerance codes.

If I unplug the ram, I get an EML light, plug it back in, it goes away. So there is some form of connection there..

You mean around plenum, bagpipes, inlet manifold etc? No obvious ones, and idle is fine...

Oh dear :(

Best bring it over for a tech2 session, we'll see what MAF is doing...

Need to fix the errors that ECU can see (the error handling generally isn't tested that well, so possible with this error, the rear multiram doesn't work).

Ah Ha... Maybe some sort of limp-home strategy has disabled it... Only explanation if the ECU can still detect its' disconnection I guess.

It was nearly 4 years ago. I've lost count of how many Omegas JamesV6CDX has had since then. ;D
