: Blinking Check Engine Light when accelerating??

Can anyone tell me what may be causing my "check engine" light to blink as I accellerate? The engine seems to run slightly rough, but it is not extreme...

Could be a starting point on even a Caddy?

you should try to get the codes read from the OBDII port ... usually autozone and the like will do it for you for free, but some vehicles need a more expensive scanner

If the MIL is blinking that means a catalyst damaging misfire is happening right now.
It should be looked at unless you just want to spend more money replacing the cats after you ignore this symptom.
Cheaper to fix the fault now.
