Platinum Member Tim_DS Posted September 13, 2021 Platinum Member Share Posted September 13, 2021 (edited) Still only a couple of weeks into Wrangler ownership so I'm still figuring out normal behaviour / nuances of the 2.0l petrol engine on my 2020 Rubicon. I've noticed the idle at startup is high...about 1500rpm for at least 2-3 mins. It coughs and splutters a fair bit too. Hopefully you can hear it in this video. https://photos.app.goo.gl/FkcP8BKPgHpg8JuXA After it settles it's completely smooth. I've tried a couple different fuel grades 95/97 Ron but no difference. I've read some US forums with some claiming it's normal, others not so sure and suggesting a throttle body issue. Any other owners experienced this? Normal? I just want to be confident in the vehicle while I have a warranty and before I start my build plans and dropping more $! 693794176_PXL_20210913_1835069802.mp4 Edited September 13, 2021 by Tim_DS Quote Link to comment Share on other sites More sharing options...
Platinum Member Volant165 Posted October 14, 2021 Platinum Member Share Posted October 14, 2021 Any update on your rough idle at startup? Quote Link to comment Share on other sites More sharing options...
Platinum Member Tim_DS Posted October 14, 2021 Author Platinum Member Share Posted October 14, 2021 hey @Volant165 general consensus is that it's normal. I think much of the problem was me just being overly sensitive to new car noises. There's no performance issues once at temperature so if it still bugs me when the next service is due I'll have it checked. Quote Link to comment Share on other sites More sharing options...
