I changed the spark plugs on my 2004 Maxima and when put back together it will not idle and stalls. On higher speeds it seems to run OK but gas pedal very sensitive and revs up easily. Car starts every time. I checked all my connections and seem to be OK. I did disconnect the air intake system. I did clean the butterfly valve on the electronic throttle control actuator with a clean cloth and opened ans closed the valve a few times. The car run OK at 50 KM/hr with tack at 15K. I took it to my repair shop and they said they could not get it up to temp to re-program the computer and did not have time to diagnose it further at this time. They were not able to get a coolant temp module reading.
