Had a code for ok nock sensor replaced both of them cleared code out and it
Came back on. The problems I having is hesitation and fuel
Milliage and also sounds like it ain't shiffting at the right rps for over drive it gose
To 80. Only thing I have done is put a child ait intake and throttle
Body spacer I don't have any any smells or noise
Take off what you put on an dsee if it goes away, a lot of those aftermarket air filters cause more problems than anything.

What is the code? And what engine?

IMPORTANT: If an engine knock can be heard, repair the engine mechanical condition before proceeding with this diagnostic.
Observe the Freeze Frame/Failure Records for this DTC.
Turn OFF the ignition for 30 seconds.
Start the engine.
Operate the engine within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records.
Did the DTC fail this ignition?-Go to Step 3 Go to Diagnostic Aids
3Turn OFF the ignition.
Remove the intake manifold sight shield. Refer to Engine Sight Shield Replacement (4.8L, 5.3L, and 6.0L (RPO LQ4)) or Engine Sight Shield Replacement (6.0L (RPO LQ9)).
Disconnect the knock sensor (KS) inline harness connector.
Measure the resistance from the signal circuit of the affected KS to a good ground with a DMM.
Is the resistance of the KS within the specified range?
IMPORTANT: Do not tap on any plastic engine components.
Set the DMM to the 400 mV AC hertz scale.
Measure the AC voltage from the signal circuit of the affected KS to a good ground with a DMM.
Tap on the engine block near the affected KS while observing the DMM.
Does the voltage change on the DMM while tapping on the engine block near the KS?-Go to Step 5 Go to Step 10
5Test the affected KS signal circuit between the powertrain control module (PCM) and the KS inline harness connector for the following conditions: An open or a high resistance
A short to voltage
A short to ground
Refer to Circuit Testing and Wiring Repairs.
Did you find and correct the condition?-Go to Step 12 Go to Step 8
6Remove the intake manifold. Refer to Intake Manifold Replacement.
Test the affected signal circuit between the KS inline harness connector and the affected KS connector for an open, high resistance or short to ground. Refer to Circuit Testing and Wiring Repairs.
Did you find and correct the condition?
Other than this you should stop right here as it could be a pcm problem or connection its' the #2 knock sensor that is setting this code.

Could it also have to do with the transmission if the filter was dirty and not shifting poperly

I dont' think so its probably picking up a knock someplace and setting the code. Have a pro look at it shouldn't cost to much tell him what you have done.
