Question about Chevrolet Cars & Trucks
The knock sensor simply looks for the symptoms of 'knocking'. Knocking is caused when the fuel/air mixture ignites at the wrong time in the four stroke cycle. (Too early or too late). The 3 most common reasons are...
a: The wrong standard or 'octane' of fuel is being used.
b: The wrong type of sparkplug is fitted.
c: The inside of the cylinder is coated in carbon, (soot), deposits.
Should you be using super unleaded or standard unleaded? Check which one is correct for that engine.
Check the spark plugs are the ones designed for that engine. Some can be slightly longer or shorter affecting where the spark ignites the fuel mix.
If the engine cylinder is coated in carbon the cylinder head will have to be removed and professionally cleaned.

Is this a manual trans in this truck, if so, try shifting down a gear. But yes a timing belt could cause this, but usually they wont run very well if the timing belt is that bad worn.
