During re-exceleration my engine hesitates. I changed the plugs about a year ago and the problem stopped. It recently started up again. I figured it was the same issue so I changed the plugs again on 12/11/11. This time it did not solve the problem. I have read that to fix the problem I should have the plugs changed, etc. What should I check first, second, and so on? Please advise. Any assistance that you could provide would be greatly appreciated!
