If the CEL is blinking while the engine is running. Its MISFIRING. Which is why your feeling a shaking condition. Probably due to it ingesting coolant, which is causing the misfire.
How long have you owned the car? Do you know the repair history of it?
The code has been on for about 8 months now. I just haven't had any funds to fix it but luckily I have some right now that will enable me too. Although it never flashed until today.
I've owned the car for about 4 years. When I bought it, it was around 7 months when I had the intake manifold replaced due to it being flooded with coolant. And about 7 months ago I had replaced the FPR (thanks to you guys! Thanks again!) and changed the spark plugs and cleaned the MAF since then. And the usual oil changes but that'* about all the car repairs it'* had under me. I do not know the repair history it before me. I am going to take it to the dealership by my home for a CEL inspection. Hopefully it won't be too much, I am a broke college student!
