Hey guys. Im looking at a 1995 R33 S1.5 Skyline with an R34 engine in it. The R34 engine is connected through a stock R33 wiring harness and computer. As a result a lot of pipes and wires have been blocked off and cut and i cant tell whats going on. The engine feels good to drive but will stall if you let it go to idle for too long (traffic lights). After some research i found that a commin fix for this is to remove and clean the AAC valve (hoping it not computer issues). Anyway, i went and did this today but i found the valve wasnt even connected to the wiring harness (Picture 1 red circle). I decided to ignore this for the time being and removed the valve. The inside of the valve was not too bad. I cleaned it anyway. However, I found rust in the solenoid and on the two small hose connections (Picture 1 yellow). This rust was accompanied with a bit of rusty fluid aswell. I should have taken photos then but i didnt think untill i had it all re assembled. Anyway, I am fairly sure rust is bad to have on the intake side of things as it sould be sucked into you engine. If you guys can shine some light on all this for me that would be great. Also, whats with the two hoses being connected together (Picture 1 Blue). And i noticed this pipe has been cut (Picture 2 Blue), also the idle screw does not look standard. The other red in picture 2 shows the purple plug that someone else refered to in the Cleaning your AAC Valve tute as the one which should have been connected to the solenoid. Starting to think this car might be more trouble than its worth.
Thanks in advance,
Will
