Hi Scott I have a 2006 Chevrolet Colorado 2.8L engine. Truck sat outdoors for about 4 years and I just reconstructed the entire engine and replace all sensors with new ones. There is no check engine light on truck, it runs smooth but when I come to complete stops my truck idles a little and turns off. I check all engine sensor connections and clean them as well as my throttle and ECM computer but it still does the same thing.What do you thing the problem is and can you please help me.
thank you
Could be a faulty throttle body or even MAF. Did you reset the PCM after cleaning the throttle body?

How can I reset my PCM?
@mrrangerzr1
I clean the mass air flow sensor. So It could probably be the PCM. Do you think is necessary to replace the computer?
