I have a 1999 C1500 Chevy Suburban with 130k miles. When on the highway, traveling at about 55, I feel a sputtering in the engine (it?s a Vortec). Around town it feels fine and the engine feels strong. It makes me think there is a misfire, but the plugs, wires, cap and rotor have all been replaced. I also recently had the fuel injectors replaced due to another issue. I replace the ignition module as recommended from a friend. Another friend says the problem is with the oxygen sensor. We are not experts, so I would value your advice. Thanks John (Florida)

A tech should verify the complaint,do a good visual inspection,do some simple tests such as vacuum,compression,cylinder leakage,retrive DTC’s,check for TSB’s,look at scan tool data. Feel free to omit any steps you wish.
