I just bought a 99 Nissan Maxima SE about 5 months ago. Car ran great until a few days ago. It is losing a bit a power and feels like it wants to stall. I had it put on the computer and the read out was cylinders 2&4 are misfiring. We have replaced plugs, coil packs. Checked the egr and air flow sensors. Checked the car and O2 sensors. Not sure what the problem could be. I was thinking fuel injectors or pump. Any thoughts or comments would greatly help.

If you replaced the ignition parts (Coil and plugs) but it still misses it is probably the injectors. Pull the plugs on the cylinders that are missing and compare them to the ones that arent to see if there is any color difference. May even want to do a compression test first, just to be sure they are at the same compression as the rest of the engine
