Question

I replace the timing and after replacing the timing this engine code popped up. P0172 trying to figure out why

Answer 1

recheck your work, lean means there is too much fuel.

check the list of causes below, if it is none of them you might have to recheck the timing 

fuel pressure should be 58psi + or - 5 (53-62 PSI)

Possible causes

- Faulty front heated oxygen sensor

- Ignition misfiring

- Faulty fuel injectors

- Exhaust gas leaks

- Incorrect fuel pressure 

- Faulty Mass Air Flow (MAF) sensor
