Altima rough running fuel issue

Sounds familiar! I had almost the same symptoms on my Altima. Is it misfiring too? Could be worth checking the injectors, like you said. They might just need a good cleaning. But replacing them might be the best bet. I'm no mechanic though!

Thanks for the reply! Not misfiring, no. Just a rough idle and loss of power, like it's being choked. When you say you had the same symptoms, did cleaning the injectors solve the problem, or did you end up replacing them? I'm trying to avoid a huge bill, but I also want it running smoothly again. I was told to expect to pay around 515€, does that sound reasonable?

I ended up taking it to a workshop. I'm useless with cars, honestly. The mechanic told me one of the injectors was completely clogged, like a blocked artery! They replaced the whole set, and it fixed the problem right away. Best to get it checked by a pro.

Appreciate the insight! I think I'll bite the bullet and take it to a reputable shop. Sounds like replacement is the way to go. Thanks again for sharing your experience; it's helped me narrow down the problem and prepare for the repair. At least now I have a better idea of what to expect.
