In READING what you wrote, it appears that your car is difficult to start and pretty much is rough while running....It also appears that your are randomly replacing parts...How did you verify that the parts your have replaced had failed? I suggest you get a basic manual like chiltons or haynes as well as a decent digital volt/ohmeter, then do some testing. Pay close attention to map sensor test and manifold air temp. Having a good fuel pump does not insure that your injectors are clean enough to deliver a good spray pattern This will not show up on any test...you need to actually look at them. There are other items to look at but I think you will likely find your problem in what i mentioned. (you already checked for vacuum leaks, right?)
Good luck!

Only someone/company with a Tech2 can do as it connects to your cars computer (ECM) and once in there you can select the option to watch/measure or less / plus the fuel consumption.

Sounds like the ignition coil is getting bad.
