Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your vehicle.
If your Liberty is throwing codes for the ignition coils on cylinders 1, 3, and 5 (P2302, P2308, and P2314) but not on 2, 4, and 6, this suggests a problem affecting just one side of the engine. Since you have done some work on the car, it is a good idea to check for any possible damage that may have been done to the wiring harness, causing issues with the ignition coils on that side of the engine and your intake air temperature sensor. Also, I would carefully comb over the wiring to ensure all connectors have been resecured. The strong gas smell and P0305 misfire code suggest that unburned fuel is making its way through the exhaust, likely due to the coils not firing correctly.
A potential issue could be a shared ground or power supply problem for the ignition coils on that side, especially if the wiring got damaged or the connections were affected when the engine overheated. Another possibility is that the coils themselves have been compromised due to the heat.
Given the complexity, I recommend having everything checked by a professional to ensure you address the root cause, not just the symptoms.
