Syzygy05 Posted May 2, 2018 Share Posted May 2, 2018 It's only been one time, that I have distinctly noticed it just a few hours ago. When I started up the car and put it into Drive it slightly stuttered, enough for me to say what was that, but not enough time for me to check the RPMs and notice it dropping. About 1-2 minutes after that I stopped to let a pedestrian cross and the RPMs dropped to around 300, bouncing around in that area, and you could hear the engine struggling to keep running. I gave it some gas to accelerate and it went back to normal idle speeds 30 seconds later. Have any of had any experiences like this before? The car only has 10000 miles on it.

Grizzled Posted May 3, 2018 Share Posted May 3, 2018 Sounds like a misfire to me. The question would be is why? Fuel, spark, or compression. Injector/spark plug/coil..... Link to comment Share on other sites More sharing options...
Syzygy05 Posted May 3, 2018 Author Share Posted May 3, 2018 Wouldn't the engine light come on for a misfire? Link to comment Share on other sites More sharing options...
Grizzled Posted May 3, 2018 Share Posted May 3, 2018 It should, but mine went a while before it finally threw a code. Same symptoms. Link to comment Share on other sites More sharing options...
MrCobbs Posted May 3, 2018 Share Posted May 3, 2018 Did this happen recently and in warmer weather? In my old 16 I did have shut offs when stopping but this only happened when the engine was warmed up. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Pilot1226 Posted May 3, 2018 Share Posted May 3, 2018 Lot of things going into the engine. Start with easy stuff first: engine air filter, mass air flow sensor, etc. before you start getting into plugs and stuff. You using top tier fuels or the bargain bin gas?

I would not be concern, did you just start the vehicle? Cold starts has the Trunk Monkey all upset. Once it is at operating temperature he will go back to sleep. I would highly recommend using good quality of gasoline (Top Tier gasoline). If it happens consistently then you have a concern and service technician should take a look.

YeuEmMaiMai Posted May 3, 2018 Share Posted May 3, 2018 what are your MAF and fuel trim readings when the car is acting up? if they are abnormal, you have a starting point. Link to comment Share on other sites More sharing options...
Syzygy05 Posted May 4, 2018 Author Share Posted May 4, 2018 I'm using Shell, regular gasoline as the manual states is recommended. >did you just start the vehicle? Yes, it was a cold start, ambient temperature around 75-80 degrees. It's only happened once, might be a fluke. Link to comment Share on other sites More sharing options...
Ovcoursitsilver Posted May 4, 2018 Share Posted May 4, 2018 Yes, it was a cold start, ambient temperature around 75-80 degrees... Huh? That's not a cold start! Try a -30˚ January morning before sunrise. Probably takes the engine a few minutes running to reach 85˚ on those days. Just kidding! And no help at all.
