Since I blew the fuse my ABS light has been on and when i am driving no matter what rpm I am at , when i pu the clutch in it goes to 2000-2500 untill i go below 12 mph then it goes back downto regular idle. I dont know what is going on. I don know if it has anything to do with it but my motor only has about 300 miles on it
 
Is it with the A/C on? My car does this alot when the A/C is on, and sometimes when it isnt on. I have heard that is is common and not to worry about.
 
The idle speed goes up when you are moving, so it is more likely to idle surge.

Treat this like a normal idle surge problem; check the BISS, pressure test, etc.
 
Again kpt is correct. The 1gs have a reed switch in the dash to tell when the vehicle is moving and the ecu then adjusts the idle up to compensate for future braking. The 2gs have the speed sensor in the tranny.

It would be my first guess that you can turn your biss down some. Try setting your base idle with the plug jumppered as shown in the manual.
 
well i pulled and replaced 1 10 amp fuse and the idle problem went away and my anti lock light went off but i still cant get my pocketlogger to work it alwats says check connection :cry:
