Can’t say for certain..
Though there are a growing amount of cases where doing a complete fluid flush (3 gallons or more) have worked on vehicles that have had the strawberry milkshake.IMHO,
I would try a complete fluid flush first.
If it works all well and good, plus you’ll save the cost and labor of a major replacement.
Might look at installing a external cooler and by pass the radiator all together.-

Unlikely a bad O2 sensor if that is what is displayed.
Unless your map/maf sensor is miss reading.
At this point I still say get a proper smoke test done on the engine and EVAP
Why your so adamant about not going to get it done is beyond me.
Unfortunately, with out starting the process of elimination via testing, you can fire the parts cannon and pay the costs without solving the issue.You may have a sticking caliper, not uncommon.
FYI, many times when a brake hose fails, it is internal.
The inner hose collapses, so there is no visible signs externally.
A external sign would be a leaking or burst hose.Injector cleaner is only designed to clean injectors.
It doesn’t add any more fuel to the system.
Just as a reference, your total fuel trim (adding both STFT & LTFT together) should be 10 +/- anymore the ECM may display a CEL.
Here’s some info you might find useful:Will you pass inspection?
Not without all the readiness monitors passing I would think.I’ll say this again.
Without seeing the vehicle, my first thought is a vacuum leak.
You’ll need to have the engine and EVAP system properly smoke tested and a skilled tech to perform the tests.
I’ve seen techs pull their hair out while doing smoke testing.
Some leaks are difficult to see.Ummmm you should have used Silicone-based brake grease is designed for caliper and wheel cylinder assembly work, not anti seize.
And yes, if your resurfacing or replacing rotors you should install new pads.Just curious…
Did you clean and degrease and clean the rotors prior to installation?
It also maybe the pads you installed…
Couldn’t say for certain, but they may not be the correct compound for your vehicle.Ok,
You started out with a random miss fire and a lean condition.
You state the shop changed the injectors.
They changed the injectors based on what exactly?
Did they perform a flow rate test on the injectors?
Did they mechanically or electronically fail?
Did they perform a fuel pressure test?
Did they check for pressure holding.?
Did they test the pressure regulator?
Another concern…
You state the shop doesn’t own a smoke machine.
This is cause for worry, a smoke machine is a basic, needed tool for testing.
I have one sitting in my basement just for shade tree mechanics on the weekend.
This would makes me wonder about their capabilities to properly diagnose and trouble shooting a vehicle.
On the shop invoice, did it state what and how the diagnostics were done exactly?Well if it’s in good shape and you like it and plan to drive the wheels off of it.
By all means.All depends on how you value the vehicle.
Is the vehicle in good enough condition to warrant the cost of the services your looking to have done?P0171 lean condition
Commonly caused by a vacuum leak
Have you looked at freeze frame data?
Have you performed a proper engine and EVAP smoke test?
You appear to be resistant to actually doing the called for proper diagnostic testing in favor to a parts cannon fix.
I doubt anyone will offer up a course of repair without having a certain amount of proper diagnosing being done.Steam usually dissipates pretty quickly. Look at a pot of boiling water
Burning oil is usually thick and hangs around a longer timeIs that steam or burning oil?
If it is steam, it’s most likely:
A blown head gasket
Warped head or block or both
Damaged head
Damaged block
If it is burning oil:
Bad valve seal
Damaged piston ring(s)
Faulty PCV
Blown gasket
Your going to have to do some diagnosing.
Check for CEL codes
Compression test on all cylinders.
Leak down test all cylinders.Best of luck ..please keep us informed.
Did you seriously try that smoke test by yourself???????
Here is a little science for you…
While doing a smoke test, it is required that a minimum of positive pressure be maintained into the system to allow the smoke to escape from any possible leaking area.( keep that bit of information in mind )
Now you start pumping up your homemade smoke machine to begin filling the engine intake ( BTW, did you remember to fully open the throttle body butterfly during the testing?)
Now what happens to the positive pressure your applying while pumping when you stop pumping to begin inspecting for any possible leaks in the engine compartment, under the vehicle, back around under the fuel tank and by the filler neck?Concerning your spark plugs ….
If NGK’s worked and were the correct fitment for your engine.
A new set of replacements should cause any issue(s) UNLESS…
They were improperly gaped
Or if they were counterfeit NGK plugs. Yes that is a thing these days, you can look up counterfeit NGK spark plugs.
Mixing grades of gas, though not a great thing to do should not cause any major running issues. -
