Thread: Rough idle only when in drive

Did you check the vacuum "T" under the S/C? That's a common place for a leak. Also, maybe the EGR pipe?

Yeah,the lines around that area look brand new. I sprayed it just to be sure, still did nothing. I haven't really checked the EGR. Is there anything in particular to look for? The 2 hoses from the EGR look fine from what I could see. Should I pull it off and give it a look?
