Ive noticed a fairly consistant engine shudder at idle. Ive since chalked it up to my ETD, but not that its off I still get the shutter...

At idle, and the tach stays dead on ~800rpms...

It will be like a full litteral one second twitch...

It feels like its miss-firing. However, during normal driving there is no problem.

Only at idle...

Anyone else have this?

Mine has started doing it with the 60# injectors, I chak it up to the table being too small to describe the injectors correctly...

 

I have it also and my car is bone stock. It pisses me off like crazy

 

mine started doing that after about 5000 miles, i'm now at 15000 and my car wont push itself out of first gear, my #1 and #4 plugs foul on startup and i'm having it towed to the dealer. No idea if there's a connection, but get it checked out.

 

That sounds sorta like a valvetrain issue...

I checked all my plugs last night, and other than needing to drop down to a 1 step colder plug, they looked fine...

 

accoring to the TSB for our ignition system it has something to do with the coils or the ICM. i'm having them check that tonight.

 

yah mine shudders at idle its like someone lightly shakes my car every once in a while i get so pissed when i feel it.

 

Yeah I am bring it in for service tomorrow. (For about 10 things)
