My PT Cruiser 2005 Limited 2

My Pt Cruiser 2005 Limited 2.4 Turbo automatic trans started to not be able to maintain a steady speed while keeping the gas pedal in the same position, Fluctuates. Then now when I get off the gas it doesn`t seem to be coasting as it used to. My Cruise Control has also quit functioning and if I full throttle the car when I`m driving at around 55 mph, it seems to go into neutral and the rev limiter gets involved. I check for codes using the key method and these showed up but I can`t find them anywhere to see what they mean, 2074 and 1697. I had an issue with the car stalling after putting it reverse, but it was due to broken & dirty battery terminals that I replaced about a week before this problem came up. I hope you can help me my daughter needs her car.
