I've checked all the vac lines, they are all new and they look good, I used 7/64" rubber hose for vac lines after my top swap, what vac should I be seeing at idle. right now i see 13-15 in. vac and after it kind of chokes and recovers I will get about 10 in. Hg, is that too low?

Also I've noticed when the motor is cold it will not act up. Once the temp gets above 140ish, it starts to idle like crap.
