weird, mine was doing this today, when i come to a stop it idles around 800 rpm, then car does a little shake and the idle goes up to 1000rpm and then settles down at 900. Then moves down to 800 rpm again, shakes a little and shoots up to 1000 rpm then settles again at 900 and so on.......is this really normal or is my engine trying to tell me something?

 

well mine doesnt shake...its just goes 890-900 all the time back an forth..... i have a HKS turbo timer and thats how I can tell that my RPM 890-900 everytime. the turbo timer has an option where you can see your car's idle.

 

mine does that shake. it worries me =/

 

mine does it too, I try not to think about it

 

yes, wait, no, well, maybe.

 

I only notice it when I have the A/C is on. I think its the car dropping to idle + compressor kicking in at the same time.

 

Mine does the shake too. It's mostly when coming to a stop in reverse and then right before I put it in first. Apparently it's normal but I I'm not a fan of it.

 

would a ETD help reduce that shake?

 

Sometimes when I'm coming to a stop I hit the clutch and RPM's are at 1200 till I come to a full stop it go's back to normal.
