Just confronted a new problem with my Buick.
When I start car I'm only getting 10 in of vaccuum at idle. It used to always be at 14 in vaccuum. Car seems to struggle staying on and motor is shaking. Idle was about 750 rpm, TPS .44 and inspected all hoses. Car was running fine until this past weekend when it shut off on me when I was about to park. Ever since then car had problems. I changed spark plugs, O2 sensor still same problem. Can the MAF cause this problem? Or a bad coil or wire. I also check all fuses they were all good. My motor has been rebuild and it only has about 500 miles on it. I do have C12 in it. Any ideas I'll gladly take! I'm out of ideas
