MY CAR SOUNDED LIKE GO-KART UNTIL ADJUSTMENT. UNTIL LESS THAN 7 MONTHS LATER MY CAR SOUNDED WORSE THAN BEFORE. I TAKE IT BACK THINKIN I AM GETTING FREE VALVE JOB AND WAS TOLD MY SPARK PLUGS WERE ALL LOOSE AND MY COIL WAS DAMAGED. ANOTHER 500.00 BUCKS THAT WAS THEIR FAULT. WHEN I MENTIONED THAT CAR HAD NOT BEEN WORKED ON BESIDES OIL CHANGE SINCE LAST VALVE JOB, THE SERVICE ADVISER TOLD ME THAT REMOVING SPARK PLUGS ARE NOT DONE DURING VALVE ADJUSTMENT. EVEN THOUGH I HAD TO RETURN THE NEXT DAY BECAUSE VACUUM HOSES WERE NOT PUT BACK ON DURING LAST VISIT. I CALLED ANOTHER HONDA DEALER IN WILMINGTON AND WAS TOLD SPARK PLUGS ARE ALWAYS REMOVED AND GAP CHECKED.
