I just had the catalytic converter and exhaust manifold replaced on my 2001 Corolla. Also just got all new spark plugs, oil changed, and new brakes.
Lately when I drive long commutes (highway), the car seems to be running improperly. It will occasionally hesitate or hiccup -- I think this is the right term, instead of a smoothly running sound from the engine, the noise comes in little waves. When I stop at a traffic light, occasionally it will not idle right--once it completely stalled out and I had to restart it from ignition. It's worst in wet weather, but does this in good weather as well.
