Check engine light came on while driving?
I drive a 1996 Honda Accord LX coupe. The car already has a hole in the exhaust by the heat shield. I was driving up a hill and suddenly my car went from slightly loud to really loud to where my car vibrates when I accelerate. A few seconds later, the check engine light came on. I don't suspect anything to be wrong with the engine as it runs just fine and the sound comes from underneath the car.
Anyone have any idea what it could be?

Anyone have any idea what it could be? I'd expect a P0420 from the exhaust leak.
The first rule of troubleshooting: make everything right, then work on the remaining problems. Fix that exhaust. Did you check to see if your muffler is still there? Why not look under your car? The hole probably upset the oxygen sensor, sometimes there's more than 1 in an exhaust system.
Or maybe you ripped it out by hitting something, which is why the sound was loud. It's a pretty safe bet it's a problem with your exhaust system don't you think? Did you get the CODE number, I can't give you any answer without the cod being identified. Since I said that, your O2 sensor, might be bad (a wild guess) Until you get the codes read there's no reason to even try and speculate. Go get the codes read for free at an auto store. If it's a lean code or anything related to 02 sensors get the exhaust leak repaired first, erase the codes and see if the CEL comes back on. The OBD II system only monitors sensors, not exhaust leaks.

- Check engine light, open door light, and batterie light all came on and won't go off? 2000 Honda Odyssey I already had the altinator replaced it a month old. The batterie almost a year old. Would the belt need be changed or something else?
- A light on my dashboard a triangle with an exclamation mark came out a few times already while I'm driving? So this light keeps coming out randomly, it is a triangle with an exclamation mark! Inside and it won't allow me to keep driving. This happen to me in the freeway just now on my way to work. What is it? I have a well taken care of 2006 Honda Odyssey.
- Engine Light Came Back On? I have an 05 Honda Coupe with a 2.4 manual, but as I was driving it one day the engine light came on. Took it down to the mechanic and they scanned the code and found it was an oxygen sensor. Light when away after replacement. Day later the engine light came back on.
- Honda crv engine light came on. Had the code scanned. Mechances said to replace distributor? The engine light is on but car still works fine. The light has been on 10 days. Will a new distributor get that light off?
