I have a 95 suburban 5.7L TBI. when it is warmed up chuggs and sputters when i give it more than a 1/4 pedal. I discovered that my coolant temp sensor was bad by pulling the plug on it and the check engine light came on, but it runs way better and does not chug. I understand that it is sort of a default mode now but when i replaced the sensor it ran like it did before. My qustion to you is what is the proper way to rest the ecm code in the computer? I installed the new one without reseting the computer, and it ran bad. Then i unhooked the battery, installed the new sensor, then hooked the battery back up and it still runs bad. What should i do?
