Your flat out wrong, maybe you should do some research before you try helping people.

When MIL is on and it flashes as you drive the car is suffering from major misfires that can damage engine components and the catalyst.

If it is flashing then it indicates a critical fault, hence why the engine is in limp mode. The result can be because of a critical sensor failure (e.g. crankshaft position sensor, camshaft position sensor, VVEL position sensor) or because of a misfire. Obviously the first step is always to immediately read the code to determine the next step of diagnosis - the very first thing I said. System readiness test failure on start up will also cause the MIL to blink, but in a different fashion, 20 seconds on, 10 seconds flash. Sure in the OP's case it was a misfire event but for the purpose of general information I was trying to point out that the MIL light can indicate different things.

Rather than attacking other posters why not refer to the service manual with specific information? I don't think I fed misinformation to anyone, so the responses are unwarranted.

The misfire code is P0300 and is common. If this is the code, its not a big deal.....it can damage your cats.....but nothing else. It will also make it hard to pass emissions....if you have emissions in your area.

I dont have cats......so no worries for me.

Want a cheap code tool? Go to obdcom.com and you can get a laptop OBD2 code program and kit. It will read the code and clear it. $87
