car was running like crap, replaced the vvt solenoids and the phasers, and the whole timing assembly.
Car still doesn't run well and now it's dropping these codes

P0303
P0174
P0022
P0021
P0020
P0012
P0010

Car also makes no power until 3000 rpm and surges when cruising.

Ive exhausted my resources and really need help

How many miles are on the motor? How old are the battery and alternator? My two guesses are either alternator or a timing chain jumped a tooth. Both are somewhat common and cause some strange issues. Also Id pull the spark plug on cylinder 3 and check its condition. Its throwing a misfire code for just that cylinder.

Have you had both load tested? Alternators for 4.6s seem to be pretty hit or miss whether rebuilt or remanufactured. Even with those miles I wouldnt brush off timing chains jumping a tooth.

It's possible at least one of the new phasers may have been installed a tooth off on the timing chains. Something to check out.

Did it drop those codes before replacing the timing assembly?
