Hello all, I have a 1991 carry dd51t that starts fine with high udle, drops down after warmup. Unfortunately when after driving fir a bit the idle will just hang up when coming to a stop or while shifting gears. Once I stop at a light for a while it will slowly come down but as soon as I start driving again it goes up and hangs...seems to only do it after it warms up..any ideas? I have already replaced all vacuum lines, sprayed linkages...any help much appreciated..
