I Desperately NEED HELP
My car desperately needed some repairs. My trusted mechanic replaced all 8 ignition coils and spark plugs. Now My car isn't shaking at all anymore when idling but here's the problem.///The check engine light came on after doing a smog check(probably because i haven't driven it yet)the smog check mechanic said to do a 60-100+ mile drove cycle.///And i noticed something BEFORE driving, my car usually has a 13 mpg range but it LITERALLY had 5.5 mpg/// I then started doing the drive cycle. 60-70 miles on the street and 200 on the freeway(until now) but it's only gone up to 11.2mpg, and only on the freeway it goes up/// I scanned my car using the autozone scanner and it emitted 2 codes p0174 and p0401. I'm not even sure if I completed the drive cycle or I simply need to erase the codes myself, I literally don't know/// My question is do I still need to drive My car so it can reach the desired mpg of 13-14 and then clear the engine light and the codes myself? But I'm my opinion overall the car doesn't shake when it's idling and feels pretty good
PLEASE ASK ME QUESTIONS.
I'm literally paranoid because I can't stop stressing about it (the codes)and the fact that I don't have a mechanic knowledge makes it worse.
If yall can recommend me to another subreddit that can help me, I'd be grateful
