Just got a new Crate engine running and it idles like at 1400 rpms. I checked for vacume leaks and do not have any. I checked the timing and it right at 0. Throt linkage is ok no binding problems. No codes. I have not drivin it yet. I just can't get the idle down. any help would be great.
Is it running on a carb/TBI, or injection? Year make model please. Does it have a computer? Did you set the timimg properly using the computers advance? If it is an 88 or newer chevy truck your timing should not be at zero. With the advance you will be 3 or 4 degrees out. Post back with additional info so we can help.
