I'm trying to help out a friend with a 1997 2WD Dakota with the 3.9L V-6 and 5-speed manual transmission. He tells me that he must run at least 89-octane gas in it, else it pings. I want to check the ignition timing for him, but neither of us have a manual for this truck, and internet searches have been unsuccessful. Can anyone provide the timing specs and any other important information (idle speed, what needs to be disconnected, etc.)?

Thanks.
