Air-con idle up TD42

Post by blackmav »

After adjusting my fuel I now have a high idle speed when the air-con cuts in.

There's an FICD actuator under the air filter box that lifts the ile speed when the air cond is on ...It's adjustable.

Get someone to switch the air con on & off and have a look under the air box firewall side . Hope this helps.

You will probably find that by adjusting your fuel your idle will also have changed slightly with out air con too.. just adjust your idle to 500-600 with out the aircon and it should be right

Didn't get a chance to look at it today, but I did adjust the idle previosly ,but the when the air kicks in it idles up a fair bit. Bearable but not in city traffic with a 3 inch straight through exhaust. :D
