P0300 Chevrolet -

Question

I have a 1999 Chevy Tahoe 5.7L engine. I recently replaced 2 of the 4 O2 sensors and the crankshaft sensor. I also replaced the spark plugs. Truck ran smooth all along but I noticed it was a little sluggish on take off. After replacing sensors and plugs I noticed power I forgot the truck had. Then the light came back on. Truck still running hard but I am getting the P0300 Code.

Answer 1

Sluggish on take off, you may also need to replace the sparkplug wires,
