your engine code means "big leak" in the evap control system, this system has alot of pieces, but you are looking for a vacuum leak most probably, look at your vacuum hoses, and refer to the vacuum diagram stuck under your hood for routing, see if you have a bad hose, or disconnected hose some where. these are small vacuum hoses that attach to the purge valve, air filter housing, and charcoal cannister. let me know what you find.

Testimonial: "Found the leak on the purge control valve. The hard plastic vacum line had holes worn in it from vibration. Thanks"
if you have a no spark scenario i would check your crank sensor located at the top left side of the harmonic balance pulley.the crankshaft (about 11'oclock) a 2 wire plug with a sensor on it check to see if it is damaged or unsecured. this sensor can cause no spark if not working correctly. This sensor is based of frequency not voltage testing is difficult, just make sure that there isnt too muck air gap. and that it is secured.Lastly may want to check timing possible that the belt has jumped some teeth and she has fallen out of timing. maybe a bad tensioner The coil will adapt i think up to 10 degree, ****** or advance. Good luck
