Idling

[Nihil]

I'm going to throw this out there cause its been bugging me, but ever since ive had my car when I'm sitting idle every few seconds I feel a slight jolt coming from the engine. Anyone elses do this? I can feel it through the shifter and with my feet on the floor lol. Its like your just idling smoothy and then a quick little shake, rpms don't move.

Does it do that when the engine is cold?

 

[Nihil]

don't think so, might be due to higher engine rpm while cold, ill check this week and see

I think I know what you're talking about. I noticed idle was much more smooth when I initially changed my plugs and the same goes when I do an oil change. It's way better than it was when I had factory plugs and dealer oil, but I will start to notice it again awhile after an oil change. Dont know for sure what it is or what's truly causing it though

drives me crazy sitting at a light and I feel the little shutters, no idea what it is almost feels like its missing or something but don't think so

Mine idles funny too. Installing new plugs this week and hopefully that clears it up.

Yea I get that when it's cold and sometimes even when warm. It runs great though so idk what the deal is, I'll probably check my plugs this week

Mine does it too.. I assumed it was misfires..

Never got any warning lights or nothing tho.. also don't hear any knock. Mine especially does it when coming to a stop after a hard pull.. which with me, happens all the time

I don't have that at all. Smooth as glass for a 4 cyl.
Maybe it's an Auto vs Manual thing??

 

[Nihil]

That's the other thing I considered was maybe its the gearbox, but AR306 says his does it and he is auto.

Mine does it when the engine isnt warmed up yet. I feel like the NGK spark plugs helped a lot though.

I've got this as well. Auto here.

Well we have a good mix of tuners in here so we can reasonably rule that out. I feel like it might be because our plugs are a step colder. I bet some fresh stock plugs would fix it. Although it's prob still best to have the step colder

 

[Nihil]

it did it on stock plugs and on ngk 1 step colder
