the problem. when i start my car in the morning it idles rough and it will idle smoothly after a few minutes. when i drive the car i feel some hesitation as i get above 40 to 50 miles per hour. my rpm gauge does go up move in the typical normal fashion. i thought it was my spark plugs and spark plug wires so i had them changed and my car ran fine, but the issue reared its' ugly head again. i only have this problems when i start my car in the morning after it sits for 10 hours plus. when i drive my car throughout the day the problems disappear and i have gone to two shops to try to fix the problem. unfortunately the car runs fine when i go to the shop and they are unable to diagnose the problem and no code shows up. please help.
