Default 02 impala 3.4 HELP!!

I have a cylinder 3 misfire and also a code for the tps. It recently was misfiring on cylinder 2 so i replaced plugs wires and coil pack and fuel injector. Know it scans #3 misfire. It only does it once in a while and i am tired of throwing money in the wind to fix the problem. Also just put new head gaskets and lower intake manifold gaskets. Any help would be awesome. Don't want to throw another 100 injector into it if I dont have too... Thanks

Try a valve job on #3. you may be surprised at the results, although if you are a mechanic of any sort, you will know that it is a shot in the dark. Good luck!
