Broken EGR line. VERY rough idol

[Dr Mordekaiser]

Ok, so I just installed a set of TM headers in my 99 mounty and everything seems fine except I feel like the engine is gonna die at idol. I drove it around the block and I was afraid to go very fast at all. I did break a couple of vac tubes. The green one that connects to the EGR valve and a white one that connects into the engine.

I thought it might be misfiring dude to spark plugs... But I'm not sure. I don't want to shell out tons of money again at a shop.

Could the EGR system be making it rough and almost stall??? Please help.

Thank you.

Sounds like a bad vacuum leak, when I unhooked my vacuum line to pour sea foam in it would almost die at idle.

Fix the vacuum lines you broke.....
