So been having a boost issue on 94 auto. Usually it ran 12-12.5 on gauge. Car was down for a while 2-3 months, but got it back on the road. Now I'm seeing it struggle to hit 10. Checked the intercooler duct connections and vac lines, all seem fine, but still only got 10. Odd thing is last night I had no trouble getting it to hit 12-12.5, but today could only get 10 again. No codes. Any ideas? Looked into belt slipping or pulley, but pulley doesn't look worn and belt is fairly new. Car runs smooth and fine otherwise.
