I own a 2004 Chevy Impala with the 3.8 liter engine and 200,000 miles.Recently has developed a problem. Car starts and idles like it should, I can drive 30-40 mph and it is fine once I accelerate it starts bucking like a wild bronco and goes into limp mode from what I am told. I recently replaced the cam sensor,throttle positioning sensor, and 1 coil pack.(it’s due for plugs and wires) Here are a list of codes it is showing,P00D9,B3200,P1374,P1361, & P1362. Any help will be greatly appreciated.
Looks like you may be looking at multiple issues. (Not surprising at that age and mileage.)
