what is: P1188  
Linear 02 Sensor / Compens. Resistor Short to ground

What I do know is:  
I replaced (bank1 Sensor1) O2 & replaced my old fuel filter for a new 1.  
I also checked my intake for any leaks, haven’t found any.  
I have had my codes reset twice and after driving for 50 mile each time my check engine light comes on

any other ideas?

clean your MAF & reset the computer

then go from there
