Chevrolet Repair: throttle body injector, chevy s10, vacuum leak

Question
the throttle body injector on a chevy s10 idles too fast.how can it be corrected

Answer
Don...Did you replace anything? The throttle body receives its information from the computer. the computer is watching the oxygen sessors,tps switch,engine rpm ,map sensor ,baro sensor and a few others. Grab someone who knows how to read the data on a scanner and get me a few readings tps voltage and tps switch voltage are critical.Also check for a vacuum leak or egr malfunction.
