I have a 2011 eco with just under 200k miles. I replaced the turbo/wastegate due to oscillating boost pressure. Guessing the wastegate actuator was bad. I've never seen vacuum on my boost gauge and still don't. The idle tends to run up to 1500 and back down around 1000 over and over again. I've...

Need help. 2012 Chevy Cruze LS 1.8 is hesitating when at a stop. I did a tune up on it a few days ago but nothing really changed. Does this sound like a misfire? It's worse when the A/C is on. I just want some internet help before I take it to my uncle who works at a shop. I'm thinking it's the...

After I filled my tank with local Co-op diesel on May2 it has been running really rough until warmed up.It misses,stumbles when trying to accelerate and the engine vibrates at idle.The mileage has gone from 31 to 25mpg (all city). It seems to point to fuel but i'm wondering what issue would the...

Started the other day filled up gas then took off from gas station immediately get a red light. After stopping for the light after a few seconds it acts like it’s gonna stall. Up and down idle. When I take off it’s ok when I get onto a 55 mph zone I speed up engine shakes and revs real high...

Hello, everyone, just had a CEL come on my 2012 Chevy Cruze 1.4L Turbo. Used a code reader and it said P0171 and P0496 which I guess reads to lean and and issue with the EVAP system. After reading some posts on similar issues (everyone here seems to be a great resource and wealth of knowledge)...

20k on a 17 hatch turbo. Just started idling rough while in drive or L6. Idles fine in park. No warning lights on dash. All other acceleration/performance fine. Just idle. Any ideas what to expect when I take it in?

2013 Chevy Cruze 1.8L 78K miles Car has rough idle after warm up, idles perfectly at about 800RPM before warm up. Feels like an intermittent miss while driving and gets worse at a stop to the point of stalling. I’ve searched for answers but haven’t been able to resolve the issue. There...

Certified 2015 1.4T with 49k, purchased in 2016 with 14k. Engine is idling rough & seems to want to stall. CEL came on last Sunday. Ticking noise when running. I had the cruise control on today at 60mph, completely flat road & MPG indicator was erratic - bouncing from 20mpg to 45mpg to 30mpg to...

I have a 2014 LTZ Cruze, 1.4L with 128,000 miles. I've noticed that it idles a little rough and when I'm at a stop, it the engine will surge up and down a little. It runs good overall but it definitely is not as smooth as before. I did a fuel injection cleaning (or whatever it's called) about...

Hi all. My daughers Cruze is having a little problem. I noticed the idle is rough about every 4 seconds. Runs fine for about 3 seconds, then a hear a noise like air escaping and at the same time the engine is about to die or run rough. The noise is coming from the valve cover on the top left...

I have a 2014 Chevy Cruze Eco, 1.4T engine, 6 speed manual, US spec. I've actually owned it for about a year now, and this has been a problem from the moment I got it. In hot weather, it will occasionally just stop providing boost. For a while I wasn't sure it was specifically cutting boost, but...

Hi All, I have a 2012 Cruze 1.8L (non-turbo) 121,000 miles with Trifecta's tune. I noticed the car has sort of a rough fuel cut off. Meaning when I take my foot off the gas (most noticeable at lower speeds/gears) the car jerks as the fuel is cut off for fuel econ. In rush hour traffic this can...

So my Chevy Cruze 2012 LT (1.4 Turbo) has been rough idling since October. It stalls when it idles in park and will turn off. I have replaced the Ignition Coil, Spark Plugs, Fuel Injectors, and a few sensors ( Will have to ask the mechanic again on that one, as he just did it Friday ). My due...

Hello, I have a 2011 1.8 Cruze that has a mystifying issue. I have a check engine light coming on with p0171 code. Oil is showing up on top of the engine frequently even after having the valve cover gasket replaced. When I drive the car there is loud squealing or sputtering that stops when the...

I have a 2014 cruze lt 1.4t 103k on it. For the past month i have notice it has been running rough only in idle. ive narrowed it down to either the maf sensor or the pcv cover. Is there any further testing i could do to find the exact problem. Or is it best to take it to a mech to find out...

I bought a 2015 2LT because I liked my 2014 2LT so much. The 2015 only has 15,000 miles on it but the car idle is loud & rough. I can hardley tell my 14 is on when I am at a stoplight it idle is so quiet. Did they change the engine? I believe it is the same 1.4 turbo.
