Vacuum problem, I think?
 

I think there are some spaces around where my MAF fits into the intake tube going to my upper intake on my 1994 GT. I've tried to push it it as far as it can go and tighten down th clamp as much as possible but the MAF keeps slipping out. Will this cause vacuum leaks?

best way to check for vaccum leaks is with carb cleaner or wd40, spray it around the suspect area, and if the idle changes = vaccum leak..

I dont recommend spraying Wd-40 in the general direction of the mass air meter.
