1999 Suburban Stumbles
Help me please!!!! Here is how it started my 99 burb with 5.7 failed inspection with a misfire p0300 I did a tune up cap rotor plugs wires pcv valve etc... Code went away and came up with bad 02 sensor bank 2 sensor 2 I replaced it.... it idles fine but when you drive at low speeds it seems to stumble if you hit the gas you accelarate fine and dont notice. No codes so far since reset. In last 200 miles fuel pump has been replaced as well as transmission was rebuilt......any ideas??????
