Own a 2002 5.3L Silverado with 198,000 miles and have been experiencing white smoke at start up since 100k. It has not been consistent but usually happens in the morning...The white smoke has also been observed during the day but rare. I'm getting close to 200k and I'm currently trying to figure out multiple codes. These are the following codes:
P-430 Catalyst System Efficiency, Below threshold(bank 2) and
P-300 Random Misfire Detected
Recently replaced the 02 sensors and have not checked if one of the above codes disappeared. Will run to Pep Boys later this week to check codes..
Please Advise
