1998 Grand Prix SE 3.8L. 184k miles. Just a little background. A few days ago I noticed that as I was driving the car it would hesitate and then go back to normal driving up until until I turned a corner. The car completely stalled. It started right back up and idled fine. Got it back to my place and opened the hood. Pulled engine cover off and low and behold there was a mouse condo built up on top of the motor. I cleaned it all out and noticed a small wire that had the covering chewed to the bare wire. the wire was intact so I covered with electrical tape. Seemed to run fine for a while and now I get hesitation while driving down the highway again. I hooked up a code reader and it gave me code P0171. I cleared it and I get no check engine light. Not really sure where to start?
