the basic ones can olny do just that. Pull the codes. If the service engine soon light isnt on, that type of scanner wont tell you anything. If the light is on, take it somewhere and have the codes pulled, advance and autozone do it for free.

This type of diagnosis is hard not being on-site. You have to find out if the problem is fuel related or ignition. Maybe check to see what the fuel pressure is. You can also rent a fp guage at advance or autozone. I'm not sure of the spec though, maybe 40psi. Someone else on the board will be able to help with that.

If you can revv it and keep it running, its odd, and makes me lean more towards a fuel/air delivery problem more than ignition related. But I guess one never knows.
