See what codes are in memory, autozone and advance will check them for free. Post them here. A flashing SES light indicates a misfire and will probably have a P0300 series DTC in memory.

well i cant take it to autozone because i have to wait until my girlfriends sister gives me the title there having a huge remodeling project done to there house so there staying in a hotel for the week i should get the title this coming up week. i was thinking about cleaning the map and the maf to see if it runs better but im getting gas well smells like raw gas and black looks like carbon coming out the tail pipe but i was thinking thats because its running so rich. so what could i do until next week parts wise?

Without diagnosing the problem, (ie. retrieve DTC's etc) anything that you do would be a guess. Check with the owner and see how many miles since it was last tuned up, what was replaced, what brand of parts were used, etc etc. Find out anything you can about the maintenance history and let us know.

well i got it running it was the cap and rotor there is no check engine light anymore.

Glad you got her going, and thanks for posting back!

yeah now my other blazer is messing up i cant ever get a ahead with these things.
