latest updated , today I decide to wake up an hour before I used to go to work to try to figure out the problem with the car . Apparently this is it. I try to start the car with the aem and crank over but not start (again no spark no pulsation) my tuner told me to disconect the battery for couple of seconds but I forgot the 1/2 wrench at the shop so i decide to disconnect pin 33a only (12 volts battery back up power) this is used for the internal datalog. I disconnected and wait like a minute plug it back and the car started right away .so this mean that the harness and or sensors are on working order .(also I notice the car idling a little richer than usuall around 12.5 it used to be 14.1 to 14.5 also cruising is around 13.1 it used to be around 15.1 . i talked to my tuner and he told me he encounter a simillar problem couple of years ago he said it was an internal log download problem. Does anybody have this problem before? how you fix it? Thanks...Omar
