rough acceleration at low rpms

Shortedaman · 10-23-2018, 01:28 PM

got in the car the car yesterday and was on the highway and noticed if i tried to accelerate the car would feel like it was misfiring. so i take it easy and the ses light pops up for like 2 minutes. i come to a stop and it idles rough for a second then the ses light went out. it stumbles in the lower rpm range once its over 3500 or im not punching it its fine. ran the code reader and nothing showed. thoughts?

I'm pretty sure you need new coil(s).

It should show up on any code reader though, go to pep boys or Napa or whatever and have them read it out for you for free.

Have someone in the car with you, and have them check the codes as soon as the SES light comes on, or have them drive it and you check the codes.

I have the Carly Gen2 WiFi adapter. It works very well, I think I'd like the bluetooth adapter better (better chance of being able to use it with other apps like Harry's Lap Timer and DashCommand)
