I have two question. First let me explain i found dead cylinder on my civic and decided to buy a new injector for it, so took them out they had alot of build up on them so i cleaned the three out and replaced the one i thought was dead turns out it was just the ground wire on the injector but then it starts blowing out white smoke so i put the old one back in and just cut out the cylinder from running(i only been running on 3 cylinders but still runs great just not as much power). but now car runs like crap feels like its hesitating and bogging a little. Did a compression test on all cylinders am getting very low compression #1-80PSI #2-85PSI #3- 35PSI #4- 80PSI. Just wonder if anyone can help me trouble shoot these two problems because im on limited funds. It would be cheaper for me to buy a whole new head w injectors in it at yard instead of replacing all new ones

Those numbers are all out of spec, but cyl3 is completely shot. Combine that with the white smoke you mentioned, and you need to test for exhaust gas in your coolant to verify a blown head gasket. You can get a "block testing kit" from your local parts store.
