I have a 2003 Xterra. I’m having idle issues. I’ve tried the relearn but that didn’t fix it. New throttle sensor. New knock sensor. New air mass. I don’t know what it could be.
It’s the v6 3.5l. 2 wheel drive.

What is the idling issue? Fast, slow, both? Has the vehicle been scanned to see if there were any codes? Why were those specific parts replaced? We need more information so we can assist you.

need to check fuel pressure, fuel trims, look for vacuum leaks, ...
Sorry I was filling this out on my phone, and I’m still new to it.
it’s idling up and down. When it’s cold it idles up to 2k. Slowly increases and then it’ll idle down a little then it bounces up and down. Like tapping the gas every second. 1,500-2000. Constantly. I scanned it. No codes. I replaced those parts bc they were the only thing I knew where to start.
No codes.
What about live data? Codes are just the bare beginning of the diagnostic process.
