Yeah, it's not a radical cam based off the profile and how it runs. It also has a Hughes dual plane intake and long tube headers. I'm sure that combination might more than what OBD I can deal with.
I feel like I have the vacuum leaks fixed. The Hughes intake doesn't have a provision for the EGR valve, so I have the vacuum lines routed to the controller and duty cycle valve to make it think it's still there.
I couldn't find the 1994 FSM, only the 1995. The wiring schematics were a little different in some places as far as color code and routing. I just filled in the blanks with "educated guesses."
Thanks for the advice of using an app to track mileage. I want to keep the original Swinger speedometer since it's in good condition and only available for two years. I put a 36 tooth speedometer gear in the drive from the transmission, but it reads higher than actual speed. I need to do the math to get the right tooth count for the 3.73 gears.
