put vac to egr with vac pump and see if it holds a vac to start with and while doing so with car running at idle the car should start to stumble if all ports are clean
Thank You. To clarify,you suggest a Vac Gauge inline between erg and erg mod?. My error light is very intermittent and maybe Vac levels won't tell me much. I appreciate you comments.
