Got this truck about a year now, ran fine no problems. running it every week lately. last week it started to stutter, hesitate and almost backfire under power and wont make power or shuts off. What could it be? truck has 89,000 miles. Throttle position sensor? idle sensor? anything else throttle body related? it idles but you can hear it not ideling correct anymore. Mostly when truck is warm or hot is when problem is bad, it stalls. if cold does not do it as quickly.
