P0128 Chevrolet -

Question

I have a 2007 chev colorado 5 cylinder vortech...I was told I'm getting this code P0128. This suggest some type of cooling or warm up issue. The check engine light is intermitant.

The truck starts fine in the morning but later during the day chokes and sputters after starting for just a few seconds....

Any idea's ????

Answer 1

Most likely the thermostat is stuck if the car is not overheating or have any leaks or the coolant temp sensor is bad.
