Idle and other stuff
Just put back my car together, with new t-blots clamps and silicone couplers. At idle is 15Hg right? Also whenever i am in the gas and coming up to a stop, I push down on the clutch and RPM's drop to almost 0 and then it comes up up. Any Ideas? I and going to try reground the MAF 1st and see what happens

Do a pressure test, and then look for a vacuum leak.

i made sure i clamped all the silicone hose down properly. But i will make a tester and find the leak.

15hg i was told is a Vac leak. At idle it should be at 20hg is this correct?

15inHg. is considered to be a vac leak, if you don't have cams installed. Cams can lower your vacuum reading some, but should still be between 16~18inHg.
