My 87 starts great in when cold but seems flooded to start warm, the high idle stays on a long time and after driving for a while (too Long) half hour or more on a warm day at over 1500 RPM, but when it comes down it idles too slow and wants to stall. No codes so far. I have changed the Temp coolant sensor and cleaned the MAF, new distribitor cap and rotor but little difference. Any help would be great. Thanks
