No codes just for stereo amp. I have about 153,460 miles on the car I purchased almost 7 years ago at 142,379 miles on it I don't drive a lot only to save my family when they cars break down. My question is I did purchase a new throttle body from amazon because it was few dollars cheaper than Rock auto where I purchase all my parts from. I installed all new parts but only thing has not been changed is the starter. I installed it and I and used my new Topdon Phoenix Plus 10.1 scan tool to relearn the throttle body and then took it for test drive, but it just does not seem the same as when I bought used. Should I put old one back on or purchase a new one from Rockauto.com Oh! Here are some of parts I installed before the throttle body: Bosch Fuel Injectors Double Platinum ACDelco sparkplugs & ACDelco coils.

Delphi fuel pump new ACDelco thermostat new belts and pulley new power steering pump and brand-new battery alternator.

I know every hate 4.6L NorthStar but I believe when buy use you should replace parts it like new car just without payments oh! yeah i change my oil every 3,500-mile use only synthetic oil Mobil 1 or ACDelco synthetic.

Also, what do you think about Cadillac CT6 2018 turbo?

Also tell me what you think about my new tool: Topdon Phoenix Plus?
