Rough idle on cold start

[TakeAwayTheFear]

Just picked this car up over the weekend. When I went to get the car it fired no problem at all, but was struggling to run and died a few times. Once it warmed up and I test drove it, she ran great! Idle problems were gone.

On sunday while diagnosing power monster problmes, I found a vacuum leak along the firewall near some check valve. I replaced the check valve and the line with the massive hole in it and now it starts much easier but still has a pretty rough idle until its warmed up.

As far as I know the only mod is a cone filter and the car supposedly has 54k miles which I dont doubt. Im definitely going to get scanmaster soon!

Any ideas?

Thanks!

Take the vacuum line off the egr and plug the vacuum side of the hose

Thanks! I plan to get a block off plate anyways. While I was in the area I found the vacuum line that comes out from the intake valley and goes to the charcoal canister was unplugged!!! Plugged her in and bam no more idle problem. .......
