When im in the lower rpms (anything below 3000) its super sluggish but only after the car has been running for a while, ill almost floor it and it will just bogg down, struggle a couple of seconds and then just open up and take off. This happens in any gear as long as its below 3000. I have been told that its due the EGR staying open and messing things up. My check engine light is on and im throwing the P1518 code. Also i have an orp, and i was wondering if now that i dont have a cat if the exhaust was too hot for the EGR and messed it up. It only died once after i replaced my fuel filter and new spark plugs and wires, so those things were not due to the car shutting off im guessing.
