Definitely check the O2 sensors too! I’ve read they can cause similar issues with performance and might throw that code.
Thanks for the tip! I’m hoping this is just a simple fix. Anyone know how much it typically costs to replace the O2 sensors?
It can vary, but I’ve heard around $200-$300 for parts and labor. Definitely worth it if it resolves the issue!
Yikes, that’s quite a bit! I hope I don’t have to go down that road. Maybe I’ll just try cleaning them first.
Spark plugs? Should I be looking for any specific signs that they’re bad?
Look for wear or burning on the ends of the spark plugs. Also, if the engine is misfiring, that’s a strong indicator they need replacing.
Yeah, I’ve felt some misfiring. This is turning into a real headache!
I’m really thinking that might be my best option since I’m out of my depth here. Thanks for the support, everyone!
I’m definitely facing the P305F issue on my '14 Malibu. It’s been a headache! Glad to see this thread.
You’re not alone! I did some research and found that it could be a faulty injector or even a bad spark plug. Looking for solutions here too.
I had the P305F code pop up, and it ended up being a malfunctioning fuel injector. After I replaced it, the code was cleared! Success story for me.
That’s great to hear! Which injector did you replace, and how much did it cost?
I replaced the #5 fuel injector, and it cost around $200 with labor. Definitely worth it to get rid of that P305F code!
For those DIYers, don’t forget to check your spark plugs! I recently did a routine check and found mine were worn out, which contributed to the P305F.
Good point! I’ve been thinking of changing mine too. Did you notice any improvement after replacing them?
Absolutely, the performance improved dramatically after the spark plug change. It’s a simple fix and can save you from bigger issues!
I’m considering taking it to a trusted mechanic. Recommendations anyone? I don’t want to get ripped off.
Thanks for that! I’ll definitely look into it. Hopefully, they can help with my P305F.
I had this code too, but I’m starting to feel like I’ve got the curse of the Malibu! How common is this issue?
It’s pretty common! Many 2014 Malibus have struggled with various engine codes, including P305F. You’re definitely not alone in this!
