Thanks Peter,

Thanks for a late night reply.

I did change out all the plastic hoses and rubber connectors. I did clean out all the Connectors for dirt and such. I did remove and replace the tubing for the arc valve and egr.

I did rotate the proportioning valve to its maximum.

I do not have any leaks and only need more vacuum from the IP pump to the vac amp. I believe the signal to the amp is 6 inches from the proportional valve. Out to the trans is 15 or so. Would it be a good idea to take the valve off the IP and take a look at it.

I hope that that is not worn out too. It seems to work fine just not enough vacuum


Thanks for the help
