Well it all started on my drive to MN from NJ, about the time i reached chicago and traveled around 800 miles on my d15b7 with 178k miles.

When i was stuck in traffic the car would shutter at low idle. Like the whole car would shake and it felt like it was going to die.....it still got me to MN and then it got me back to NJ(great little thing)

I am wondering if anyone knows what this could be, i have new wires, spark plugs, a whole new dizzy, i tried fuel treatment(STP).....nothing worked

 

Is your idle really low? like 500rpms? cause that makes the car shutter, but I wouldn't even know where to start to fix that unless it is just idle and not caused by something else...
Are you throwing a code?

 

Check to make sure one of your vacume lines didnt come off. If u get a leak it could cause a rough idle.
