My Mustang (2005 GT) has been in the shop for over 2 weeks getting a timing chain job done. Now they are taking even longer because the left side is not firing properly these are the codes they told me P0345, P0349, P0357. Any experts in here that could help me out, and tell me how fast this can/should be done. Thank you.

They finished the timing job. Been a week since they are trying to figure out the codes and driver side misfire
Sounds like they finished it wrong tbh. If they just did a timing job and it’s throwing timing codes, it ain’t right.

They need to pull the front cover, inspect the timing marks and make sure it’s actually in time. If it isn’t/wasnt, then I would also make them inspect the cylinders for any piston to valve issues, because even if you are off by only a few teeth, PTV can occur.

Do NOT take the car until they make it right.

Had similar experience with a workshop here - got the car back not repaired and decided to buy a garage lift.
The problem is, even if you get the car back with no error, you cannot trust them, engine can have a hidden damage now.

yea i did the timing like 3 times now on these 3v,,
very very easy..

but a few things to note here..
** are they using fords timing kit ? or a knock off?
** if the phaser trigger arms get bent during the install ,then the cam sensor will trip a code saying the bank is outta time,
*** the cams installed correctly .?

as said before , this shop seems not so smart..
if i can be an honest dick for a moment,
these are again, the exact reasons i do all my own work , period,,
because even if i dont know what im doing, i have enough available
information and aptitude to get it done ,
and thus far i am doing pretty good ,

i know not everyone has a garage and tools,, but if you do , no excuse ..

While I agree with the sentiment, didn't he grab the box without the stones and then die trying to correct his own error?....just clarifying.....

Agree with doing your own work sentiment. Up to the point where the repair is not exactly apparent or cost effective.. Example: Have had two instances of Coil on Plugs (COPs) going bad. (Last instance was the week before last.) Since I've seen the same symptoms before (engine bogs and bucks) rather than swapping COPs around in the hopes that I find the right one/s I'd rather take it into a dealer for a diagnostic which typically runs ~$200; helps me narrow down the issue and worth it in my mind vs throwing spit wads at the wall.

That said. Once I have a definitive answer I always do the repair myself unless I just can't due to physical ability or the job is beyond my expertise. That usually has been the best trade off in my experience and saves me hundreds if not thousands in inflated repair costs. The most recent visit to the dealer said COPs 7/8 were bad which the tech moved to 5/6 to validate... (problem moved so I'm thinking easy fix). Then the service person quoted me a price to replace those two COPs - $800... for two COPs; or get this $1800 for all 8. Yep, $1800 for about an hour's work (even if you're slow). I literally told the service person that was insane... He said yeah he told his manager it was unlikely I would accept the quote... yeah, ya think?

Anyway, I took her home and after about 30 mins; it's literally one 7mm bolt and one electrical connector per COP (Yeah, I'm slower than molasses these days (and supercharged so I had to move some things out of the way)). So, two OEM COPs later (which I already had) she's running fine again and I saved at least $800. Of course I'm thinking to myself the entire time "It's no wonder everyone avoids the dealer." Don't get me wrong, I don't mind paying a fair price... but I'm not going to be financially raped either. Going forward I don't see that repair costs will improve so as long as I'm able to do my own repairs I will do so. And when I'm not? Probably time to let someone else enjoy her.
