R32 idle speed adjustment

My R32 used to idle way too fast (1500-1700 rpm) for 10 or so seconds after I pulled up at the lights or what ever, before it dropped to 800rpm.

My mechanic adjusted the idle control device at the rear of the inlet manifold by disconnecting the plug then screwing the adjustment in until it was right then he reconnected the plug. Apparently it was way out.

It's been much better since he did this.

My sons recently purchased R32 has a similar fast idle problem and I said to myself "I know this one" and pulled the plug off the controller and tried to screw in the adjustment. The only problem is that it's already screwed in all the way (1200 rpm idle) and screwing it out only increases the idle so there must be another problem.

Does anyone have any ideas what it could be or how i should adjust the idle properly?

I have the same problem but its not my AAC vavle it can be an intake leak. Around the plenum or throttles, use sum aerostart . Spray it around the intake and throttles. if the engine picks up revs then you got a leak there

      Squealing is aids. Street cars, weekend track cars are not allowed to squeal.

      Stock speakers / head unit functionality

      By GTSBoy · Posted

      The front speakers in an R32 are 6x4s which is a shit size. You can fit 6.5" woofers or coaxials in there but you need to make a mounting board from MDF. I have a post on here somewhere showing what I made. You can fit 6.5" in the parcel shelf easily enough. If upgrading the head unit, the stock speaker wiring is not really fat enough to run big speakers (ie the wires into the doors or up to the rear) because the amplifiers are located next to the speakers. Running new speaker wires front and rear is a good idea anyway.

      Been ages since I did anything on the s15 but got some time and motivation over the weekend. Brakes are now fitted with fresh seals, hardware and pads. Bolted up with the alpha omega brackets, just waiting on 2 fittings and sensors to Bleed them. With that done moved onto the fuel system. The injectors have been cleaned ,flow tested, new filters and orings.  Made a bracket to hold the surge tank with surge tank and pumps mounted then plumbed. Roll-over valve done too. Need to make a new loom and add individual relays for it all. Had new flange welded on inlet manifold for a bosch 74mm DBW throttle body.  Coolant bypass hose done with some fittings welded on now then soda blasted. Waiting on sensors to arrive to install and pwr for radiator and intercooler still. Getting to point of buying an ECU and looking like may be going something else as link doesn't have enough inputs.   Work has been awesome with first trip to Perth and now on the way to Darwin looking for a good result there.

      It always makes me laugh when I hear things like this, when I was a young bloke I bought a old Mk1 Escort, one of my mates said "how do you expect to have a girlfriend in a old car like this", my reply was "if she doesn't like the car she can walk, and if she is more interested in the car I drive than me she can fark off" This is how you can tell if you have a good woman, they care not about things like the cars you drive or what it sounds like Pandering to crazy obsessed women who care more about how they look in a car than the person driving it is something that I've always kept away from Not saying my Mrs isn't crazy at times, but it's typically me being a idiot that incites the crazy 🤪

      But where's the fun in that, for me it isn't about the money, I have money, and I have time, I enjoy the process of things, the picking parts, the "adventure" of it all, and for the bits I can do myself, the actual work is enjoyable, well, varying levels on enjoyment on hard to reach things like that farking thermostat I just changed
