check the setting on the automatic choke . loosen the 3 screws on the mounting ring and turn the cap a few points to allow the choke to come off earlier.. If it is heated by pipes from the manifold ensure that the hot air is getting to the choke operating bi-metal spring. If electric ensure that the current is getting to the heater in the cap.

My 1992 Chevy Blazer S 10 is revving really high when it starts


i have an s10 that would rev up high. i hooked up my scanner and it didn't give me much information, so i started researching. it took a while. i got my manual out and looked up all of the sensors in the fuel system. i even paid some web site $10 for help {wasred my $10} and they were no help. so i researched all of the sensors and found out their symptoms when they malfunctioned. the culprit turned out to be my water temp sensor. here is how it works, when you first start your engine the water is cold, the sensor sends out the information to the brain [warm me up] so your engine idles high to help reach operating temp quicker. when the sensor malfunctions it will send the wrong info to the brain [i'm cold] so the brain revs up the engine in an effort to get warm .i replaced the water temp sensor and the engine is back to normal.
