Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Hi I would like to help you out. The symptoms that you are describing are that of a weak ignition coil. Each spark plug has its own coil on top of it. When they get weak they break down, run rough and cause misfires under light acceleration when giving it more gas. If the misfire is bad enough the check engine light will come on. You can check codes to identify the faulty coil. If there is no codes you can view mode 6 data to view the affected cylinder. A bad catalytic converter will not cause these symptoms.
