Make sure your ignition is set up correctly and wires going to right cylinders. And check coil. Was it doing I t prior to the work that you did? It may be a basic engine problem. Also check for a vacuum leak as well and check fuel pressure with a gauge auto parts rent it.

Then it wasn't the parts you changed to correct it. If it had a misfire code like 300-308 those are very hard to diagnose and apro should do it because it can be any sensor causing the problem. Your fuel pressure should be 41-47psi key on engine off test that, vacuum leaks then compression
