Default Odd code after plugs changed

I'm running a fairly aggressive tune in my hybrid motor. I changed the spark plugs today and it wasn't the stock iridium plugs, but I put in the NGK Copper "v-power" cheapos.

Soon after I started it up CEL came up and had the code read at Advance. P1130 (A/F sensor malfunction). Are the plugs causing this or is the sensor really bad?

I'm guessing plugs.

Yes that is the only code...checked it three different times. Cleared it each time and same code came back.

cracked ceramic neck or improperly gapped plug?

it almost certainly isnt a plug issue...it IS almost certainly a problem with the front o2 sensor

I guess I'm sorta confused that a sensor is fine the day before, change spark plugs, then sensor bad. hmmm

Guess I was hoping for a $25 fix rather than a $130 fix...

Guess its a $155 fix...ordered the plugs and sensor

...This is a stretch, but would having a car tuned with a dirty and gummed up MAF sensor, then cleaning the MAF after the fact have the same result? I gave the MAF a good cleaning when I changed the plugs. My guess is not; however, improbable is not impossible. -and I would think the car's learning curve would compensate after a ECU reset, which I did as well. -I could also be over thinking this too. lol

Definitely isn't the plugs. Sheathing around the 4-wire harness was melted through... -The wires themselves weren't burnt, or at least from what I could see. But I'm putting my money ($108 for a new sensor to be exact) on pure noob error and not making sure the wire was out of the way of the passenger side bank.

ho hum, oh well. -lesson learned.

Thanks for the input UncleScotty!!
