my 05 SLT is starting to show a noticeable hesitation at operating temp. No check engine light yet. It has 230,000 miles on it, so I want to stay in front of any problems with it. Today I added a bottle of Chevron injector cleaner to a full tank. If that doesn't help where do I need to look next?

 

When is the last time you serviced it beyond oil, like Air Filter, Plugs, etc?

 

Air filter, I change usually twice a year. Plugs, I guess I'll start there, because just thinking I haven't changed them in at least a year maybe 18 mos, and not the best plugs they sell at that. Thanks.

 

No problem. These trucks are temperamental I have found
