The light blinks because the pcm is detecting a misfire. The two evap. codes listed should not effect the way it runs. How many miles and when was the last tune up performed?

its got 123,000 i put new plugs in it last week to see if that would help but did not i havent gotten new wires for it, but i starts and runs good for a few minutes as long if it is cold out but if the weather is warm it runs bad as soon as you start it

The cap, rotor and wires would be my next step. Get it running ok then try to tackle to Evap codes.

Hey friend, what type of spark plugs did you put in the car the first time? If they're anything other than the correct Delco, Denso, or NGK plugs I bet thats the source of your misfire.

Do you have access to a scan tool? At this point I would examine all the lines of data while the vehicle is running, if you can do it both on a cold morning when it runs good and when its warmed up and runs like crap. Your trouble codes all too often don't tell the whole story as to what's wrong with it.
