I have a 2004 Monte Carlo and my check engine light has started to flash. I have been having trouble keeping it running, it stutters and does not want to keep running. It smells like gas and I have a hard time starting it. I have replaced the spark plugs and have checked the coil assembly and have spark. I have also replaced the air intake valve. The plugs and the valve where replaced prior to the check engine light starting to flash. I have seen that you have had this question asked already but we have already gone through the steps you suggested and the problem is still occuring, could it be my catalitic converter?

First thing you need to do is have the codes read, Post the results with the code number(s). Even if the service engine light is not on, there should be freeze frame data stored.
If it won't make it, buy a cheap scanner, they can be had for 30-40 dollars, a good investment, since they cover all cars sold in the USA from 96 on...
If the light is blinking, it means possible damage to the converter...service it right away!
