ok...here is my problem...I hogged out my cats and installed 02 sims in the rear. And ever since the car hesitates at low rpms, like when i am just cruisng down the road in OD. When I step on the gas it clears up but when i do , a giant cloud of black smoke exits the exhaust. As you can imagine...this is very embarrasing. Also, when the car is missing at low r's the SES light is blinking and when i floor it it stops blinking and just goes to constant. Does anyone know what would cause this?
