Have you downloaded the EFI bible? Will probably help you out some...Having the FSM (Factory Service Manual) for your model year will also help out quite a bit, as the EFI bible makes reference to various sections, page numbers, procedures...etc...etc. You can get the EFI bible at the following url:

The best thing to do instead of playing the guessing game which is expensive would be to perform all of the test procedures at the 35 pin connector for the ECU which is listed in the FSM with a multimeter. performing these tests will get you pointed in the right direction to what the cause is.

Thats my best suggestion. Hopefully you own a meter and a FSM :)
