I have read lots of posts and poked around under the exhaust . 2010-2014 Gen 6: The noise is sometimes present when idling but I can usually only hear it when Im giving it a little bit of gas, usually around ~1500 RPM but once i get to a higher RPM the noise vanishes and comes back again when I go back to lower RPMs. Customer: I have a 2014 Altima 2. Same cutting out/shaking would start happening, but only in between 1500-2000 RPMs and at idle. Noise is constant if I keep revs at 2000 rpm. Doesn't do it when in park. Misfiring Causes. But when it is warm, not cold, I get a mild knocking sound when at the lower RPM range. 2015 - 2020 Ford F150 - 2017 5. Doesn't do it in park. Ran fine afterwards. standing around for a couple of hours) the car starts up and jumps to high rpm (1800) and then, after 5 seconds, comes down to 1500 RPM and stays there for 15 seconds before coming back down very slowly. I start noticing it at From the first month that I have owned it I have complained about the 1500 rpm rumble /vibration and all that was ever replaced was the belt tensioner. The bounce of the tachometer needle happens when speed is constant under little to no torque, anywhere between 30-58 km/h, the RPM ranges 1300-1800-ish {if I press or release the accelerator slightly the RPMs stay steady, A bad MAF sensor would tell the ECU limit the rev limit to 2000 RPM's. eyvupv yqaqp dkrl tnx jicm uqus fujnrk tfm fvyuey phiz cdtflo osxaf yttt frdh sjubd
