Yeah I got to enjoy one of the many benefits of having and driving a Cruze too, that of spending quality time with my tow truck driver. And it's all because of the hard work put in by GM's Chevy engineering team to decide to code the tune for GM vehicle PCMs to put vehicle into Limp Mode when a 2% difference is detected between throttle body position sensors. It was so funny that I forgot to laugh. Gotta love that P2135 DTC and Reduced Engine Power Limp Mode safety feature. (Well not so much on Saturday when I was having an intense need for a restroom while stranded on the side of a busy highway. Oh the joy of a high fiber diet.) Gosh and as an added bonus there's no TBPS replacement kit available for the Cruze throttle body 55565489, so the lucky Cruze owner gets to buy a new TB and enjoy spending yet more time under the hood. Not an excessive amount, however, as it's easy to change out the TB. Well at least I think that a new TB is needed as neither GMPartsDirect, AutoZone, Oriellyauto, Advance Auto, or NAPA offer a TBPS replacement kit. Then again my silly problem beyond being out $130 for a tow fee, may be that my beloved Cruze may actually need a replacement Accelerator Pedal/Sensor assembly part no. 13252702. Well I'll inform this thread after I fix it. Ta-Ta for now. Cheers

1-8-2019 > All good. Bought New throttle body on Amazon for $91.45.
https://www.amazon.com/gp/product/B004JBI5Z8/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Installed easy-peasy. Torque screws to 71 inch-pounds. Ensure intake manifold bolts torqued to 15 foot-pounds. Reconnect TB,O2S1,BootPSI sensors. Tighten hose clamp holding intercooler-charge tube to TB. I used a short length of 1.75"-2.125" mountain bicycle inner tube rubber as a grommet over the Throttle Body's inlet air connector tube so Intercooler-Charge Tube connection is less likely to suck in unmetered air. Lubed bicycle inner tube grommet using a small amount of talcum power. PCM relearned new TB position sensor output quickly. Drove Cruze to work this AM (Now in morning break.) Getting 38 mpg in stop-go-surface-street commute. Engine coolant temp running max temp of 109°C/228°F.
Using Pennzoil Platinum Full Syntheic 5w-30 with a Fram TG10246 filter, Dex-Cool with "Water Wetter", NGK BKR7E spark plugs (More HP, MPG, Smoother running at low rpm idle); previously ported out internal air-dams inside intake manifold. So far intake's internal PCV intact-no oil in intercooler-charge tube or in turbo inlet compressor. Oil consumption issue was solved by use of Bar's Leak VS-1 oil additive in fresh oil change. Ran oil with the seal conditioner for three days over 250 miles as per directions then changed the oil again. No oil consumption since over 2000 miles daily commuting on Dallas freeways.

Gapped at .037" - so far no spark-kernel blow-out while running at 80MPH/2800RPM
Best Good Cheers
