Unless the coding is different for the 97 my 97 FSM shows PO301 as a general misfire detected. Code P0302 is for cyl 1 misfire. At any rate the FSM lists: Ign. System, Injector, Fuel line Pressure, Compression problems, valve adjustment, valve timing, MAF, and eng. coolant temp sensor as possible causes. That really narrows it down <img src="/forums/images/graemlins/confused.gif" alt="" /> The FSM has tests for all of the above and I can send you the sheets if you want. PM me if you want them. Again, this is a 97 manual. Mebbe someone with a 96 FSM will have something to add.
