08 Enclave. I got the random misfire code. Car would stumble and not accelerate. Ran rough and seemed to go into a "limp mode" when asked to accelerate. Changed plugs, didn't work. Changed coil packs, didn't work. Changed MAP Sensor ($35 Bosch part) ... Bingo Problem solved. Erased codes then changed oil. 2 days now, no issues

I have a 10 enclave, same engine. Trust me, the timing chains are coming. And if you don't replace the chains when they first act up, you'll be getting a new engine for $2500 to $3500 from junk yard. Oh, then the rack and pinion and power steering pump. Word to anyone watching this if you have these trucks or any car with this engine sell it ASAP. Trust me sell it.

It is a bad fuel injector causing all the problems. It makes the coil go bad And you get an OBD reading of a misfire.

The problem was/is the catalytic converters came apart and clogged the exhaust, some people may think its a battery problem because the engine its hard to crank, it does that because the exhaust is clogged

The 3.6 V6 in the Traverse is Gasoline Direct Injection (GDI). The venting gases from the PCV valve results in a carbon buildup on the Intake Valves. With no fuel vapor flowing over the Intake Vakes to clean them, the airflow eventually becomes restricted. This is a design oversight in early GDI engines. My 2011 Enclave has the same engine and had similar issues. I used Seafoam Upper Engine Treatment and fixed my issues. This however will only last so long before needing to be treated again. Your best long-term solution is to install an Oil Catch Can between the PCV valve and the Air Intake. This stops the vaporized oil from getting on the Intake Valves. The Catch Can needs to manually emptied every 1,000 miles or so which adds to regular maintenance.

Try crc gdi intake cleaner. You dont have to take the top out. And clean out the mass air flow sensor.

Maybe it was the coil pks on top of plugs. Causing the misfire

Purge valve and mass flow sensor.

Stop guessing put the scanner on and stop guessing if it isn’t the crank or cam position sensor then it’s definitely the timing chains it has 3 of them

Got the same issue right now 2007 GMC Acadia with 220K . Engine started shaking while driving. Codes P0202 0204 0206 popped. Replaced all spark plugs and fuel injectors, Codes were gone but now have P0300 code and engine still shuttering, shaking and misfiring.

My 2012 is doing the same thing. Mine is stalling at operating temperature though. Still baffled why its doing that.

Surprised that you didn't create a bigger problem when you sprayed the Carb Cleaner in all of the intake runners without checking to see which valves were open, and which ones were closed.

Thank you let me watching. Good job.

Needs a intake gasket and coil pack and plug I just did it to mine and fixed it

try drilling bigger holes in the pcv valve in the rear crank case is not breathing. causes oil build up in throttle body

Ty very much for this video 👍🏽👍🏽👍🏽👍🏽

She's definitely clean now 😁

My car is doing this and on the dianostic it gave 3 codes, control module long term reset, crank & camshaft not plausible,engine bank 1 throwing signal, but my car was doing exactly what yours was so I'm going to cross my fingers

$2,000 for timing chains??? That’s a bargain!!!

And i was told timing chains too but no sounds either or that my converters were clogged

Thank You !!

I have a traverse also. Same issue, very very dirty intake and valves. How is your engine still running?

Looks like the one I worked on a week ago. Had one bad coil and plugs were all changed

Change your oil after treating intake with seaform small parts may be moving tru your engine broken parts of carbon chips and may plug up something.

Do you still have the traverse I’m having so many problems with mine hoping your videos would help

Did you ever check the code to see which one was miss firing and recheck it again to see if it errased the code? I have a missfire on cylinder 1. swapped the coils from a different cylinder still same code, even swapped the spark plugs as well just to see and still cylinder 1.....any help?

Timing chain making noise

How is the vehicle is the engine still good

Looks like your #5 coil pack is missing.

What's the brand of the intake cleaner you're using?

My experience was I had my enclave 2010 shaking past 60 miles per hour it was coil problems I changed 2 coils and spark plugs and that solved my problem.

Shops always try to pull some money out ya a$$ 😂 you did right not bout to happen

My infiniti giving the same problem but my own is clean

My 2016 chevy traverse AWD Lt is skipping and bucking when you accelerate even trying to go up hill i cleaned out the throttle body it was very nasty gumed up black didn't do anything for it acts like transmission is slipping on it i have appointment to hopefully get it fixed. Hopefully some one can tell me what it could be any help would be appreciated Merry Christmas out there

What is the clicking noise while the engine is running?

I had a misfire , using the remote start. But using regular key ignition it won't misfire, any idea?

Please hit me up I got some questions mine is doing the same thing

That’s is too much cleaner going down to the pistons you may have made things worst you got chemicals along piston rings sound like you made a engine clatter issue that miss came from some other vacuum leak
