high idle on a XT-6


Recommended Posts

I just picked up a 88 XT-6 (5speed, diff lock). when i start the car, it runs between 1800-2000 rpm for at least 5 min. then it slows down to 1200- or so. that seems a little high? is there a idle screw on this engine? thanks for the help in advance.

When I first start the Brat in the morning it runs at over 2K for about 5-10 minutes (depending on the temp outside). Then drops down to about 1K-1.2K for another 10-15 minutes, or untill I drive it for a couple blocks, when it drops down to 800. Does your drop down to normal at anytime? or does it stay around 1200 all the time?

If it's all the time, check the computer for a code, best place to start.
