Have a 2002 GT. My engine light came one a little over a month ago. Had it checked out and it was Bank 1 Sensor 1. Heater circuit malfunction. P0135 H02S11. Couldnt get the money to get a new one for about 3 weeks. Finally after changing it and the code went away. But about a week after. it feels like the engine cuts off fuel for about half a second whenever i give it a good amount of throttle.Thats when the engine light came on again and instantly took it to get the code read. Its still the same exact sensor and Heater circuit malfunction.It doesnt happen every time but it is very noticeable.After about a week the engine light goes away and i try to make the car do it again to try to pinpoint where its comming from, but once it does do it the light comes back on. I had a mechanic i know for a long time check it out and i drove it around the block to see if it could make it happen. It did and he said all we could do is wait until it gets worse or until something breaks because he has no clue what it could be. I really dont want to have to break it to fix the problem. The car runs fine but whenever i want to give it some go entering the highway or another place i can't really do that because I'm afraid it will do it or actually break it. I haven't really gone fast in it in a while and it kinda sucks to have a 400hp car and not have fun in it.. Any advice to help a fellow new edge owner out? I really want to get her 100% running again. Thanks!

 

Since you have already replaced the sensor, it is likely an electrical issue somewhere. http://www.obd-codes.com/p0135

 

Its not uncommon for the trasmission harness to get routed wrong if the trans was ever out. I've seen numerous occasions of the harness being pinched or chaffed and exposed wires causing faults.
