It takes longer than usual for my car to start up. When I take off it it seems you have to give it extra gas because it feels like it pulls back and doesnt want to go. After that it seems fine as long as youre driving. When stopping at a light you have to keep it idling around at least 1000 rmps by holding both gas and break to keep it steady or else it will want to die out. I recently found out it cannot stay idling for more than 10 minutes or else it will completely stall out regardless if its being given gas in attempt to keep rpms steady. When you shut it off it will not start back up until about 2 hours later. It will start for a second, idle rough and stall. I have no engine lights on. I have given it a tune up, changed fuel filter, cleaned out throttle body, map sensor, (doesnt have maf) crank sensor and ignitor control module and still no luck. Any ideas?
