Lately, my Civic hesitates when i step on the gas when at low rpms, like 2000-2500. It kinda slows down, then decides to go, then brakes some, then goes, giving me a few good kicks to the ribs. What could be the cause of this? Everything regarding ignition (wires, spark plugs, distributor cap and rotor) have all been replaced recently. I have 145k+ miles on the car, with stock motor and injectors. Could injectors go bad? It's a Dual Point Fuel Injection, meaning it only has 2 injectors and no fuel rail, so i couldn't pull the rail to see how it's squirting gas.

Could it be that ignition is to advanced/retarded? At higher engine speeds (3000+) it never happens. Also, this is a huge issue in first gear.

Thanks for any thoughts.
