My 2007 V6 Escape ‘sputters’ at 30-40 MPH and sometimes at idle with moderate pressure on gas pedal. Only happens when car is warm, never in first 5 minutes. Check engine light is not on, no codes found. Thought it might be transmission, had it serviced to no avail. Tried Techron injector cleaner, no improvement. Increasing or decreasing pressure on gas pedal clears up problem momentarily. Any ideas?
Even though no codes, you might try cleaning the idlae air control valve (IAC) and mass airflow sensor (MAF).
Seems as if you have a common problem with a bad Coil on Plug being bad. Here is a link. The problem is 3 of them are under the throttle intake. http://easyautodiagnostics.com/ford_cop_coil_escape/cop_coil_test_1.php
