Re: Weak Cam Chain Tensioner Symptoms
Sounds fishy to me. A bad tensioner will announce itself with chain noise, and even then I do not see how it would affect engine performance to a noticeable level.
The tensioner really cannot become "weak", as it is actuated by engine oil pressure. If your oil pressure light does not come on, then this is highly unlikely. There is a spring in it, but that only keeps the plunger extended against the movable chain guide when the engine is stopped. Once started, the oil pressure applies far more pressure than the spring.
