Q: Car loosing power while driving?

asked by on June 21, 2016

So I've changed out the fuel pump, distributor, alternator, spark plugs, distributor cap, alternator belts and water pump. Now I'm feeling a loss of power while driving. Used some fuel injector cleaners too in case it was that. Car was diagnosed with Cylinder misfire on 1 and 2, but I was told it was the spark plugs, then alternator then distributor. Any advice? Also car overheats regularly, but slightly. Needs to be topped off with coolant every few days. Thoughts?

My car has 160000 miles.
My car has an automatic transmission.
