Your truck’s performance decrease during hot weather could be due to a number of factors.
One of the reasons could be that the engine is overheating. This can occur when the coolant isn’t effective, causing the engine to work harder than it should. It could also be the result of an underperforming air conditioning system which puts additional load on the engine.
Another reason might be the fuel vaporizing in the heat before it gets to the engine.
It’s great that you’re attentive to these changes, Mike.
I’d advise having your truck inspected by a professional mechanic to identify and rectify the issue.
