    Hello everyone. First I'd like to start by thanking Jerry Suarez & his crew down at Discount Tires in Azusa, CA and Gabriel Alcala, a diagnostic mechanic of 35 yrs experience, at A-1 Auto Expert in Chino, CA. Just as important as fixing your vehicle is finding a mechanic who is willing to...

    Which direction does the upper gasket go for the catalytic converter go? Does the raised edge go towards the turbo or down towards the catalytic? See image.
  3. Gen I
    This a stock midpipe from a 2012 to 2015 Chevy Cruze LT. Turbo. It should work on any cruise from 2012 to 2015. I replaced the exhaust on my car and is the OEM part left over. It only has about 42,000 mi on it so it should be good for many miles after that. From what I understand. Again, pretty...

    My 2014 cruze 1.4l 150k has the cel come up for a p0420 code, there is a burnt smell everytime i step out of the car permeating through the air. Should i just go ahead and replace the catalytic converter? or is there troubleshoot steps i can do before?
  5. Gen1 1.4L Turbo
    Hello, I got a 2014 Chevy Cruze LT. A CEL came up recently while driving. I bring to the mechanic and he replace the Cat and oxygen sensor. After he replaced the Cat, he found that I have a misfire on Cylinder 2&3 but there is no any misfire code. So he replace the sparking plug, ignition coil...

    Hello folks, I hope you are all well. I have quite the myriad of issues with my car, but have been trying my best to fix them one by one on a budget (and definitely not messing things up along the way resulting in costlier expenses). My car was quoted (many months ago) for the water pump...
  7. Gen1 1.4L Turbo
    I am planning on modifying my exhaust; my plan is to buy the zzp catless downpipe and bolt in an exhaust cutout on the stock midpipe. If the primary catalytic converter is removed will the secondary catalytic converter be able to handle the extra chemicals or will it clog soon? If clogging turns...

    So I have a 2011 Chevy Cruze 1.4l Turbo that I purchased used in a private sale. After leaving the title office the CEL came on, got the code read at auto zone and it is the P0420.

    I recently had my front brakes done and the mechanic called to tell me there was a small oil leak coming from the oil feed line the feeds oil into the turbo, so I decided to have that replaced at the same time I had the brakes done. When I picked the car up there was a check engine light on and...

    Could use some insight on this one. 2011 Chevy Cruze LT 1.4 Have a P0420 and no other codes. Replaced plugs (looked to be a good burn), checked PCV system, changed oxygen sensors and replaced catalytic converters with aftermarket ones. PCV hose from turbo housing to intake was found to be...
  11. Gen2 Powertrain
    Hey all, so apparently I need a new exhaust.. not sure the extent of it yet since I’m gonna have to take it to a muffler shop. But I was looking around for exhaust recommendations. Not sure if I’ll need a full exhaust with cat or just a cat back(I may not know what I’m talking about here). My...
  12. Gen1 Service Issues
    I have a 2014 Cruze LTZ with ~110,000 miles on it. My CEL came on at the end of October; OBD II scanner gave me code P0420. I took it up to Firestone, and they replaced the front O2 sensor and burned-out catalytic converter, as well as repaired/replaced the leaking head gasket and leaking...
  13. Gen1 Powertrain
    Not sure if I posted this in the right place. But I just got o2 sensors, engine air filter, and purge valve replaced about a week ago after codes P013B, P0171, P1101 and P2270. After all that got fixed I’m getting code 0420. Dealer suspects it’s the catalytic converter. 1. Could the o2 sensor...

  15. Gen1 1.4L Turbo
    Hi, I’ve got a P0420 code and the dealer said that it was my front catalytic converter. I have a little over 80,000 miles on my 14 Cruze and I need help figuring out what caused the catalytic converter to go bad. I changed the spark plugs at 74k just for a tune up and the classic ignition coil...
  16. Gen1 1.4L Turbo
    Welcome to the house of Pain So I have been fighting with the CEL on my 146k mile 2014 Cruze 1.4t for quite some time and now I am at a loss. I have frequented the search bar throughout this venture and made some guesses of my own but I suppose its time to admit defeat and ask for help. A...
  17. Fuel Economy
    Hello guys! Do I need to buy a new catalytic converter or an injector is not working as it supposed to? Sometimes I feel the car like heavy or not responding quickly when I step on the gas(takes like 4-5 sec to kicks in), like if something were obstructing the exhaust pipe/muffler, the engine...

    I recently had my 2015 Chevrolet Cruze checked for what smelled like my engine burning. The original mechanic replaced the heating hose and said it had cracked. I took my car back to the same mechanic a week later and said it still smelled like something under the hood was burning. He identified...
