I install an AC to my car, works really good, but when it is on, of course it stall the engine because when the compressor engage, the engine must be increase the rpm to compensate.
Some one told me, increase the Idle, but I do not like this idea, another one told me :
The factory air on the early Rabbits and Sciroccos had a small solenoid valve wired in parallel with the compressor clutch. When the compressor engaged, the valve vented off the vacuum-retard side of the distributor, increasing the spark advance.
The valve was a factory part on 1976 through at least 1980 Rabbits and Sciroccos, It's pretty simple to connect, just two vacuum lines and an electrical connector.
I spend yesterday looking for this valve on google and without sucess, then today I call some places but they did not give me anything If I do not tell them the part number.
If someone can give me a hand I really appreciatte,
Thanks,
Ivan
