My guess is a cam sensor, (usually the magnet) the magnet that triggers the sensor falls out of the end of the cam when the plastic retainer fails from age. The car goes into "limp home mode" it runs bad, no performance, and bad gas mileage.

Changed out the coil packs, no luck there. Heard out may be the fuel filter, anyone know where that's located?
