Now I know this should be compensated for, but am a little unsure how.Here are my thoughts so far, on how:a) Aircon selection sends signal to ICV which compensates.b) Aircon sends signal to throttle bypass valve which compensates.c) No idead) No idea but know great place for nasi ayam.If anyone could prod me in the right direction would be appreciated.</p></blockquote><p></p>
