Did the Check Engine Light come on when this happened?
Customer: replied 2 years ago.
Yes, it did. I Opened the hood and the area near the air filter had a different tone of sound to it; I noticed that the gasket from the fender liner to the filter had opened - although it didn't look to be a real recent separation.

Also, it seemed like I could depress the pedal and it would kick up the shift of the gear of the transmission - but again the rpm remained constant at 1200.

Since the check engine light did come on... The best thing to do at this point is to scan for the "Diagnostic Trouble Codes" (DTC's) from the onboard computers. The DTC's are used as the Starting Point for diagnosis. They let you know which system(s) the fault is in. This information is of great value for correct diagnosis. As a Technician, my first course of action is normally to scan for the DTC's. If you can obtain these codes, we can more accurately and efficiently diagnose the problem. You can have these Codes read for FREE at your local auto part store (AutoZone, O'Reileys, Advanced, etc.). If you post these Diagnostic Trouble Codes here, I can obtain the most accurate information to help you diagnose the Concern, and then point you towards the correct repair.
Keep me posted...
Thank you,
