Recently I've had some problems with my car stalling out while driving down the highway. The check engine light came on and the code read that I was have random cylinder misfires. So, trying to skip all the BS I changed the plugs, wires, and coils. The problem has seemed to vanish, but the car seems to still be sluggish and when I'm at a stop light my car sounds like a diesel. On top of the fact that my car has over 150k on it and my gas mileage is less that stellar, My question is what are good injectors for my car and is it ok to go with remanufactured injectors?

Thank you
