are you going to be able to handle this

Expert:  david craig replied 19 days ago.

Hi Im David, the knock sensors as you know are picking up pings and knocks from the block due to ignition abnormalities, giving that information to the computer to advance or retard the timing to optimize engine performance. Has it ever occurred to you to check the timing?

Customer: replied 19 days ago.

Yes I have done that every thing line's up after watching several videos I'm going to Lexus and new knock sensors I think NAPA lied to me
