rough idle

[chaby_91]

My entire interior and dash will shake viciously if my ac is on. But the second the car starts moving or I rev it up the shaking completely stops.

Chaby are you i4 5 speed too or?

^that's pretty much what it does.

yeah, 5 spd.

Check the air flow sensor or whatever it's called, could be dirty, or adjust the idle

Hmmm

Iacv=opens and closes like it should
Egr = vac leak, high idle, but rough

Run seafoam, give obd reading at cold engine, idle when you have prob, w/ should be, output, actually are, where available
Rpm
Iacv
Egr
Map
Coolant temp

Hard to name, might have more, lol

Mine used to do that. My dash would shake, glove box, sunglasses holder rattled a bunch and the steering wheel would vibrate so bad it would make your hands itch. I no longer have vibrations such as that but it's not perfect. I think my left motor mount is weak, but no more interior rattles. Since then I have replaced all the small vacuum hoses, they were collapsed, put a new pcv in, new serpentine belts, and seafoam. I don't know what stopped it.

motor mounts would be my guess

^worth a look at this point

no maf on these cars.

I'm fairly confident engine mounts are not the issue here.

 

[agginline86]

My car had similar issues when my motor mounts went. Really shook hard getting up to 1000 rpm but after was fine

 

[chaby_91]

front and rear mounts are new

I also used seafoam and TKO 2000. it helped smoothe out the idle, but the issue is still present

Can't you adjust it? With that flathead screw on throttle body?
