The oxygen sensor on a 98 Chevy K1500 truck is located in the exhaust manifolds. It monitors oxygen levels in the exhaust gases and allows the computer to make adjustments for optimal performance.
A malfunctioning oxygen sensor can cause the engine to be low on power.
NO.... Not hardly.
I can't speak for that specific model but if your truck is less than 10 years old the answer is probably no, O2 sensors are very unlikely to cause rough running. More likely a vacuum leak or maybe an injector.
no
