i just bought a 001 dodge stratus 2.4l.i have driven it for a little while and noticed the spark plug wires were going bad. when i drove the car at 50mph before i was at 2000 rpm. since i replaced them when i go 50mph it is at 1500 rpm and doesn't hit 200 until 57mph. not only that but the next day i went to work in the morning and the car spins the tires at every stop sign. i know the previous owner was a kid and he installed a better transmission in it so maybe he did a few other things to.
