Aztek 6-cyl

2001 Pontiac Aztek. During hot days (>85 degrees) truck will continue to accelerate slowly when foot is removed from accelerator at speeds under 42-46 mph. If at speeds above 50 mph, truck will decelerate until it reaches about 42-46mph. RPM is between 1500 RPM and 2100 RPM when this occurs. Braking is long and difficult when this occurs. Vehicle 'groans' when at complete stop. Putting the truck into park has an RPM of 2000-2300 RPM and a very high idle. No mil or non- mill illuminates when this occurs. Turning the key off will return the car to a normal (500-800 RPM) idle, and each successive key off will lower the idle a bit more if the idle was still a bit high. Has happened at least ten times. Iac was cleaned and did not solve the problem. Iac was replaced and that did not solve the problem.
