Car stuttering?
While driving the other day my car began to stutter like it was about to shut off. It idles high and low, and shakes. While acceletating, the car doesn't move much and gets to a point where it doesn't move at all. I've changed the o2 sensor and all 4 spark plugs, and nothing. The codes I'm getting on the OBD are p0132, p0300, p0302, p0303, and p0304. The description of the codes talks about the cylinders misfiring, which is why I changed the spark plugs, but nothing. Can't seem to figure out what else it could be, need help please, thank you

P0132= O2 sensor high voltage bank1 sensor1 " O2 sensor between cat and engine" possible causes O2 sensor is bad(most common) or wire problem
P0300= random misfire P0302= #2 cylinder misfire P0303= cylinder 3 misfire P0304= cylinder 4 misfire possible causes for misfires bad sparkplugs (make sure they are gaped properly if needed) plug wires, distributer cap and rotor (or coil on plug depending on application) bad coil unlikely but check, fuel restriction( fuel filter or bad fuel pump), bad gasket for intake ( there are a few gaskets), there is more but this will give you a good start. chances are that the misfire took out the O2 sensor and it can destroy the Cat. raw fuel is going past every thing. if you can check the fuel trims long and short term they should be + 10 or -10 when added together ex. long term +20 short term -15 would be +5

year, make, model, engine size, mileage...and I promise you'll get a good answer, otherwise, not bloody likely.
