CHECK TIMING. SINCE THE DISTUBUTOR IN AT THE BACK VERY SNUG WITH THE FIREWALL IT COULD BE HARDER TO ADJUST THAN MOST HONDA/ACURAS. IN MY 7 YEARS OF EXPERIENCE AT A ACURA DEALER MOST TIMES IF AFTERMARKET PLUG WIRES ARE USED WITH AFTERMARKET CAP AND ROTOR THE IDLE CAN BE ROUGH. I DON'T LIKE TO SAY IT BUT EXPERIENCE HAS SHOWN THAT FACTORY IGNITION PARTS WORK BETTER THAN ANYTHING ON A STOCK OR MILDLY MODIFIED HONDA/ACURA MOTOR.
