I recently noticed when my car comes to a stop engine running and ac on the engine revs as if it wants to move forward. The rev isn't huge. When i am in traffic and holding down on the brakes, if i release the brake without pressing the gas pedal and allowing the car to roll forward on its own the car begins to rev.
I took off the ac but this didn't solve the issue. What i did was turn the engine off and turn it back on and it stopped. The problem is not noticeable as i start the car only when i drive for 30 minutes or so.
I am not sure what can be causing this since the only thing i did with the vehicle was full gas. I am assuming the issue can be with the fuel. I am also thinking the idle sensor could be going bad or could it be a dirty throttle body.
Any help and advice would be appreciated guys.
