Thanks for the suggestion Shadow, but I don't see any vacuum hoses coming from my power steering pump and I don't remember tracing anything that I took off of the intake back to the pump. ???

Can anyone give me a more detailed how-to on testing the ECU? I feel like I'm missing something glaringly obvious, but I don't get how you place the tester leads into a plugged in ECU.

Any help or resources would be great, thanks again.
