Im getting a check engine light and when i pulled the codes the light flashed 9 times and im no quiet sure what it means or how to fix it.

It happened after doing a tune up and it came on when i was doing 100mph on the interstate.

when i did the tune up i got the wrong plug wires but they are replaced again, i reset the ecu and the code still comes up.

It comes right on when the car is warm but if its cold start in the morning the light doesnt come on untill 1-2mins later.

Anyone have any ideas?

Thanks
