2013 buick verano. 211,529 milage total, only 110,000 total on new engine that was put in. automatic shifter and i believe its the base regular model. i own the car, i was gifted it from a old lady from my moms church a year and a half ago.
so in august last year the only codes were timing chain silonoid sensors which are common to replace on that kind of car engine. now theres codes though the roof! what do i do, and what to replace first, sensors are around 200 bucks and to fix the timing chain would be 1,500.00. if i dont fix the chain will the sensors keep breaking? What do i do? i just fixed timing chain silonoid sensors today. i put a link to my image of what the paper work says. 
These days that's just what things cost. And just like it costs you and your lady $25 dollars to have a crumby lunch at McDonalds these days, automotive repair costs at any shop are crazy.
Case in point. I needed brake pads and rotors on my car. All 4 wheels.
I can do it but I'm 65 years old and don't want to.
I called the local shops and the best price was $400 per "axle". That's $800 total before taxes, plus the "shop supplies charges" for all 4 wheels.
I'm sure I would have paid close to $1,000 before they were done with me.
I called NAPA and was able to get pads and rotors, not the cheapest and not the most expensive, for $169 "per axle". I used some online promotion codes and was able to get the cost down to $150 "per axle". $300 total for front and rear pads and rotors as opposed to (around) $1,000 the shops would have charged me.
So my tired old ass jacked up the car and did the job my damn self because for me $700 is a lot of money for "shop labor/supply costs".
I'm just sayin', These days prices are crazy and if they charge almost $1,000 to do an hour and a half brake job, is $1,500 for a timing chain replacement exorbitant?
And those 2013 buick Veranos have a known issue with their timing chains.
You got the car for free. If you want to keep driving it without risking destroying the engine you probably have to bite the bullet and do the timing chain replacement.
So how do you pick a shop? The dealer will screw you. The chain shops employ low wage beginners.
Most importantly, find an independent shop that's Better Business Bureau accredited (you'll have recourse if they screw up the job). Also, check online reviews. Understand that experienced mechanics don't work cheap. So it's worth paying a couple hundred bucks more to get the job done right by a professional with experience if you can't do it yourself
the dealer ship will charge 165$ a hour and use one finger to press on the chain and tensioner, to see if its loose. ive been told for a timing issue deeper than that, it will be 1,500.00
Yes, any mechanic will align the timing marks and check for slack in the chain
.
But once you're into the labor costs to go that deep for them to check for slack, you'd be crazy not to just replace the Timing Chain, Timing Chain Tensioner, Timing Chain Guides, Timing Chain Tensioner Guide, Timing Crankshaft Sprocket, Variable Valve Timing (VVT) Sprockets, Timing Gear Oiler, and Variable Valve Timing (VVT) Solenoids
.
They come in a kit.
And Do Not go to the dealer. They will screw you. Not an opinion, it's a fact
i dont have tools, or a garage to do a timing kit. and i dont know of any good mechanics in colorado.
That image doesn't have the greatest contrast and not the easiest to read. You need to find a real mechanic who will do some actual diagnosis instead of just reading and printing out codes.
i worked at a couple of millions airs garage for a little while, i know alot about cars. i think the plan is to replace mass airflow sensor. the cam shaft sensors codes is probably a lose chain tensioner, and at worse case scenario a skipping chain. which im sure firestone wont touch, so ill have to go to the dealer to get the timing chain stuff figured out because i dont know of a good mechanic, lol and i swear last time i was there, i think the cut my leather and vinal seats with a blade, cause its all cut up in Mutiple places. so rude. and i need to also replace the o2 sensors. other info is my pvce tube was broken for a while, like 6 months, ive replaced the pcve tube, and it was broke off from the "N duct" so i replaced the n duct that is about of the air flow system, and bought a new pcve tube for 8 bucks, the n duct was 180$. im sure thats why the mass air flow system sensor broke because of the incomplete disconnected pcve tube broken off from the n duct.
if i fix the mass air flow sensor the o2 sensor may stop faulting.. and if i throw parts at the cam shaft sensors, its most likely not going to fix it, and if it doesnt. its because the problem is timing chain tensioner, and worse case the the timing chain is off cause its having timing issues which will cost me 1,500.00 to fix.
the timing chain could also be loose due to ware and tear and it stretching.
i plan to pay firestone to do a deeper check on the problems for 119$
By "real mechanic" I mean a good independent shop that has the skills and equipment necessary to do proper troubleshooting. There's a good chance all those codes have a single root cause. Chain shops like Firestone should be avoided. Dealerships as well.
i wish scotty kilmore would loook at it for me, i dont know any real mechanics in colorado
There are tips on finding a good mechanic in the FAQ.
