What code are you getting? Â*I just went through some troubleshooting on my 96 and the P0300 misfire code was pretty misleading considering the real problem turned out to be loose EVAP purge lines and charcoal canister falling apart inside. But I did the plug wires anyway and that took almost 8 hours!
