Hi Everybody. Bobby_J here, new member, I don't know if this is the correct place to post this! Hope So. I have a 2004 Chevy Impala LS, 3.8L. I am a novice in Auto Repair and just do it on my vehicles. I just finished my first project on this car, changing MAF sensor after I made sure it was the right thing to do. did pretty good on researching and diagnosing and finishing repair. I was wondering if it would be in my best interest to buy either a subscription to an online manual or hard copy at Auto Zone since I will be keeping this car for a long time I hope. also which manual would it be best to get? Thanks Ya'll in advance.
