Thank you for the feedback. I replaced all the vacuum lines and front 1 (of the 2) controllers as well. While I was doing that I crawled under the car to give it a once over and noticed a lot of oil around the red hose. So I ordered that from Whitbread and also noticed two of the seals around the lower intake bolts was missing. I have a second controller and new set of "backup seals" coming from ECS by weeks end. I'm going to replace all the intake seals, the second vacuum controller and the intercooler intake hose this coming weekend.

I wasn't able to hook up the camper and tow yesterday because I ran out of time but on a quick run around the block (I live in the country so its a big block with no traffic) and without towing I had the car go into limp mode when I was approaching 100mph so I'm thinking there is some sort of correlation between heavy load towing and high speeds. It could have been that way for years because I don't think I have ever gone that fast that quickly in this car but I wanted to push it and make sure nothing exploded. Hahaha!

Hopefully after this weekend I'll have some time to hook up the camper and see what happens.
