ses light but no code

[ooraceredgt]

i was driving my car and the car started to miss at higher rpms. i didnt get a ses light until the car started to miss on the low end also. i used my programmer to see what triggered the ses light but no codes were found. what would trigger the ses light but not produce a code. i was thinking that maybe messing with the timing and fuel might have fouled a plug or something. any help would be appreciated. thanks in advance

My car threw P0059 one time.. my scanner wouldn't pick it up, but I bought a different one (with updated software I guess) and the code popped up. Try taking it to AutoZone and see if they get a code.

Sometimes if it's a misfire, the MIL will flash, but not stay on.. no clue why.
