i just removed my air pump and ACV, thanks to the search button, with no problems (well, we'll see once i start the car). now i got a couple questions, when i removed the ACV i saw the intake manifold check valve underneath it, a honeycomb looking thing with a suction cup type bowl on the inside. is it necessary to remove this from the engine block before i put on the block off plate? here's a pic of it on the car, and it taken out/me holding. pretty sad, my cell takes better pics than my 4 year old camera, but anyways:




and my second question is about the two electrical connectors that are left after taking off the ACV, both were connected to the ACV - do i wrap these up in elec. tape and leave them hanging there next to the alternator or should i do something about them. thanks guys.

 

Pull out the disc.
Just secure the orphan plugs out of the way.

BTW on an S5 you have to have the solenoid coil or a resistor plugged in to avoid an ECU error code.
The S4 ECU's don't care.

 

I think he has an 88 gxl

 

Since the check valve sits flush, I'd just leave it in- it's extra protection from pressurized exhaust gases blowing by the block-off plate. Your choice, though

Make sure you isolate the power wires from the switching & port air solenoids (if you cut the plugs out of the way), or you'll have some arcing and sparking going on

 

yep, 88 gxl.

thanks guys. its probably best to leave them wrapped up and out of the way - i dont want to cut anything i didnt need to. i'm putting the plate on now and i'll let you know how it goes. i JUST got my silicone couplers 5 mins ago in the mail, so today is a good day, i finish one mod and another comes in the mail =p
