Engine Performance problem
1997 GMC Sonoma 6 cyl Two Wheel Drive Automatic 155000 miles
I have a 1997 GMC Sonoma and I Have the following codes popup within the last month
P0147 o2 sensor
P0300 random misfire
I have purchased new wires, plugs, o2 sensor, cap, rotor and fuel filter. I'm going to replace these within the next week. I'm also going to check leaks in the vacuum system as well.
Anyone has an idea with the combination of these 2 codes? A guy on another forum told me he had the same problem and replaced the o2 sensor and it was gone.
Any other suggestions are greatly appreciated
have the same problem?
