Cat was running fine. Changed oil at 104,000 miles and accidentally spilled quite a bit of oil on the motor where the ignition coils and fuel injectors are. I whiped up as much as I could. Car ran fine for about 4 days. Parked it for the night, started it the next morning and it was misfiring bad and engine light started flashing.put the code reader at AutoZone on it and it detected the 3rd and 4th cylinders randomly misfiring and the cause being the fuel injectors. I replaced spark plugs and fuel injectors and now it's even worse. Any advice is greatly appreciated!

Hello, how was it "detected" that the cause is fuel injectors?
It would seem to me that the coil boots could be saturated in oil, causing the seal to be interrupted and the spark plugs to lose proper, consistent spark.
AutoZone code readers are just that. They read codes. They have zero ability to drill down into root cause.
