Don't remember seeing your prior posts, so I have no history. Has the car run this way since you bought it? I would do a compression check to see if the hardware is healthy. If compression is good, that eliminates a lot of things. If its bad you can give each cylinder a squirt of oil to check for bad rings. If still bad the valves need checking. Do a leakdown test. If it all checks good, it has to be spark or fuel.
