    lack of power and no check engine light

    I am still fighting this issue... lack of power, and no CEL, or even pending codes. and it is hit and miss too boot. sometimes it is fine, other times its not.

    Here is what I have done.

    1. pressure checked for air leaks...
    2. tune up using OEM spark plugs about 15K miles ago
    3. New turbo about 5K miles ago
    4. New intake 9 Months ago
    5. Checked the entire PCV system... all good

    I think I am going to do a compression test this weekend...

    Ready too just trade it off...

    any ideas?

    What octane gas are you running? The gen 1 Cruze engines are actually built for 91 octane and it's the ECM software that allows them to safely run on 87 octane. The problem is the ECM throws away a significant amount of power to safely run on 87. Try 91 octane for a couple of tanks and see what happens.

    I have always ran 87 octane in the car and I purchased it new about 3 years ago. The engine has about 87K miles on it. (cracked ring lands in the original motor). It just started doing this about three weeks ago... Honestly, it is starting to act just like the original motor did before it went to complete crap... just not using any oil, yet.

    ok, just did a dry compression test...

    Cylinder 1 - 140PSI
    Cylinder 2 - 130PSI
    Cylinder 3 - 120PSI
    Cylinder 4 - 125PSI

    Now cylinders 1 and 2 passed 100PSI on the second crank. 3 & 4 was more like the 4 crank out of a total of 5 cranks.

    so I am going to say I have two week cylinders, AKA, a junk motor, again..... and only 87K miles on it...

    Assuming you're in North America, it's now summer. With the warmer weather, the ECM is going to have to retard spark to prevent knock. That's where having higher octane when under boost really helps. It was the earlier model years that really had problems, but a tank of 92 is a cheap to try.

    And you say you tuned it up using OEM plugs. I suggest you remove them, check the gap, ensure it is .028 and torque them to 18ft-lbs - no anti-seize and then make sure the resister springs are free and not caught up in the rubber boot. When you pull the coil pack, check the boots for tracking.

    I'd agree with you. You've got a mechanical fault. I wouldn't waste anytime with different fuels, or spark plugs or anything.

    You should have compression number far closer to 200psi. 165psi is about as low as you can really go and not notice a difference. The 20psi variance is also as you mentioned cause for concern.

    You could in theory have a stretched or skipped chain causing low compression, but the cylinder to cylinder variance would still be a death knell. Sorry.

    and the motor only has 87K on it... I have always faithfully changed the oil every 5K. I never "hot rodded" the car either... This is the second motor..... something is not right.

    I'd question the gauge itself with those low numbers across all cylinders.

    This is a Gen 1? Have you tried a WET compression test (little bit of oil) to see what the #'s look like?

    As someone else said, these cars feel completely gutless in the summer on 87 octane. Try a tank or two of 93 and see if it perks up.

    170 is what people are posting.

    The engine needs a 11.5 piston to hit close to 200.
