I have a 2001 Toyota Camry xle with about 250,000 miles, automatic codes are p0301,p0303,p0305
Until three days ago it ran and drove great. I did get new plugs, wires and and coil packs when I got the car about 8 months ago and those were the codes it had. Now it will idle fine but struggles to accelerate.
How does the car itself drive? Do you notice any symptoms?
Those are misfire codes for Cylinders 1, 3, and 5. For the codes lookup and troubleshooting, see the excellent sticky here:

Your gonna need a scanner to look at data, don’t throw parts at it.
misfires can be caused by so many things, for example vacuum leaks, etc.
I only replaced those cause they needed to be replaced.
