I deleted my entire emission system yesterday. EGR, evap canister, and all vac lines. The only parts I left in the car are the 2 solenoids. I started the car up a little bit ago and it is now idling around 2k rpms and I got smoke coming from the exhaust. It wasn't smoking prior to this and it idled between 1k rpms - 1500 rpms. I made a block off plate at work and sealed it with rtv when I put it on. All the throttle body ports are capped off and the one that goes to the fuel tank has been routed under the car. Are there any other spots that need to be capped that I'm missing? I did do searches for the smoking thing but forgot about the idle. Surprisingly I only found one discussion about the smoking, but it didn't seem to fit what I'm experiencing.
 
Got carb cleaner or preferably starting fluid? Start it and let it idle (preferably with someone sitting inside to shut it off) and start spraying around the egr block off plate, tb, etc and when you spray where the leak is it should rev up. It's just sucking in the starting fluid and it's acting as additional fuel. Wont cause any problems unless the leak is severe enough it revs to the limiter, but that's why I suggest having someone in the car to kill it.

Good luck :thumb:
