2009 Dodge Challenger R/T throttle hesitates

Dear Doctor: I have a 2009 Dodge Challenger R/T still under warranty that the dealer “updated” with the latest computer software. Immediately after that update the car developed an intermittent throttle lag. When stepping on the gas, the car hesitates a second before responding. I’ve had the Dodge for almost two years and I never experienced this problem. The dealer hooked it up to a data logger and went for a test drive. He found that the delay is real and showed me the graph of pedal input vs. throttle body response. The service manager escalated my case to his district service manager, who referred it to Dodge engineers. Dodge came back and said the car is “operating as designed” and no repairs are authorized. Any advice? Peter

Dear Peter: There are no Technical Service Bulletins on the throttle hesitation you describe. I also researched both our Identifix and Alldata sites and nothing found. Your next step is an aftermarket computer performance download from any of the companies that offer a download. You can check Super Chips and other companies. These computer programmer companies offer a variety of programs that you can down load and then remove when bringing the car or truck back to the dealer for service. — Junior Damato, Motor Matters
