ok. i just got these codes this morning heading into work. the CEL was blinking before it finally just stayed on. MY02 is at 50k with no mods. i noticed that the car idles a bit rougher and i'm loosing 100+ miles on a tank of gas.

i did run out of gas a couple of weekends ago and had to walk to a gas station. could this be the reason? are these code to be concerned about? big bucks to fix?

thanks for the help

Maybe You Should Consider A Valve Adjust, Pretty Common In Earlier Models. Also Possibly A Ecm Reflash.
Valve Adjust Is Covered For 3 And 36 Only, It Is A Maint. Item.
I Have Seen Alot With Tight Valves, Mainly Exhuast.
