1990 MX5 Automatic engine idle issue

Postby Kallaroo MX5 » Sun Nov 27, 2011 9:46 pm

Hello all,

Yes I have an automatic 1990 MX5, the issue I have is when I put the Aircon on the engine revs drop too much and it starts to vibrate the motor.

How do I adjust the idle speed for when the air con is on. At the moment normal idle speed is aboput 900rpm, but as soon as i Put on the Aircon it drops to about 500rpm and shakes like sh*t.

Cheers
