Confirmed, I got 28 mpg on the way to Iowa. Since the roads were bad my average speed was probably 60, on the way back the average was probably low 70s, I think it'll be about 25 mpg, which is still a few better than before.

Anyway, I was wondering about the MDP (or MAP) sensor. A few people have told me to keep it until I get dsmlink, but a few have said it's not necessary. I did some looking around and RRE and a few other places say it's just for EGR monitoring, which I don't have any more. A few other places say it's for idle control.

What I'm thinking is I didn't seal the vacuum line to the tiny MDP sensor nipple and it caused a huge boost leak (P port of TB), which may explain why my car doesn't want to idle below 1300rpm. Any thoughts?
