Try resetting the ECU after fixing any issues! Sometimes a fresh reset can help eliminate old codes and get the car running better.

Has anyone here had to deal with a manufacturer recall regarding cylinder deactivation? I wonder if others are facing similar issues.

23

Yes! I had a recall on my 2012 Chevy. GM took care of it, but having that info beforehand would have saved me a lot of stress.

I appreciate everyone’s insights! It’s good to know I’m not alone in this struggle. Let’s figure out these pesky cylinder issues together.

I totally feel you! My car felt like it was having a heart attack. I replaced the manifold absolute pressure sensor, and it helped a lot!

I had similarly weird symptoms, but it turned out to be a faulty fuel injector. Replacing that made a big difference for the deactivation system. Check those too!

That’s a great tip! Fuel injectors definitely don’t get enough love. Have you noticed any performance changes after the fix?

My mechanic told me that regular maintenance is key to preventing this problem. Always check the oil levels and keep everything clean. It really makes a difference.

Regular oil changes are crucial too! I learned that lesson the hard way when my car’s performance tanked. Never skipping again!

For a more permanent fix, I’ve heard of people disabling the cylinder deactivation system entirely. They say it’s risky, though. Thoughts, anyone?

Disabling it might void warranties or affect emissions. However, if you’re out of options, it could be worth considering! Stay legal, people!

True, but have you seen those aftermarket tuners? They offer a way to make it work without the hassle too!

I once tried a cheap fix with additives, but it didn’t work at all. Better to invest in actual parts rather than hoping for a miracle. Lesson learned!

36

Same here! The only miracle I got was a lighter wallet. Quality parts save money in the long run!
