2010 Dodge Challenger SE - Tune Up

This 2010 Dodge Challenger was brought in to AAS because of two issues. One was that the heat had stopped working. Two was that the engine was running rough (what mechanics refer to as "missing") with a 'Check Engine' light. The customer also asked us to give his Challenger a tune-up. We found the heater core was clogged, so we did a full coolant flush and unclogged the heater core. Now the heat works great! Nice and toasty! 

We diagnosed the 'Check Engine' light and discovered one of the cylinders had a bad ignition coil. The engine on the Dodge Challenger has an ignition coil pack for each cylinder. We replaced the faulty ignition coil first to make sure the engine ran smoothly again, cleared the check engine light, and re-programmed the engine computer. After this, we went on to do the tune-up, so we took out all six coils and replaced the spark plugs. When changing the spark plugs on the right-hand side of the engine (the passenger's side), you need to un-install the intake manifold to get to the spark plugs. When you take off the intake manifold, it is recommended to replace the intake manifold gasket to create a new seal because the old gasket will no longer seal. After that, we reinstalled all the coils including the new one and the car now runs smooth and purrs great. This is one hot kitten!
