2000 Chevy silverado 5.3l v8 with 122000mi.
Check engine light is on and shows codes of too lean left and right bank and p0300 engine misfire. Rpms go up and down at startup and almost dies but runs fine when driven around or after it warms up. Rpms are rougher with cold weather.
What is causing this? Also, loss of power.
