I have been having a problem with my car's vacuum, I can't seem to get it running right It's very frustrating, is there any way to bypass this vacuum on this car? I've changed everything that has to do with the vacuum and still having problem I changed everything on top of this motor from plugs, wire, and cap, o2 sensor, distributor, so many things in broke, lol. Please help, I'm no mechanic, that's for sure.

Here are some guides to help with low power or engine cylinder misfires. You may not be dealing with a vacuum leak. Check fuel pressure, see if your fuel filter is clogged, make sure you have good spark to verify that the ignition coil has good output. I use the gap adjustable spark tester so I can stress the coil, making sure the ignition isn't breaking down. These are all basic things to check first.
Below is a diagram showing how to retrieve diagnostic trouble codes from the engine computer.
