Weird Idle and rough drive

[kshawn]

It looked like your knock control stayed in the .6 range the whole log. Is it not settling down to .49?

Check for a vacuum leak

I cleaned the mass air flow sensor, I changed my spark plugs, and retune the car and waited 5 minutes on idle. But no luck any other ideas before I change the injectors? Also, if I do change the injectors is this a thing that is going to keep on happening?

I think I'm in a similar position. My fuel trims look pretty bad compared to yours though. I average -10 or more ltft most of the time when I am driving unless I strictly drive highway for 20-30minutes, otherwise, on my daily commute my ltft sits very negative. I was going to change my spark plugs in the next few days hoping its not the injectors.

Dam bro I feel like it’s deeper then that possibly your cam sensor or bad coils ?
