this is killing me.


when my car is cold it pulls good vacuum and runs great. after it is heated up (25 minutes or so) it loses almost all vacuum and starts idling rough.

I have replaced all the vacuum lines and T's. I have done the started fluid check for an intake leak, no dice. I do have an exhaust leak I will be fixing today, will that cause this issue?

Check your PCV valve and tubing.. Something is expanding when hot and causing a vacuum leak
