I recently bought a 97 2.5L stick. I've posted before about it here, and done some work to it lately just because I don't know it's full history: ALL fluids changed (engine, both diffs, transaxle, transmission, coolant, brake, power steering) replaced plugs (distributor/wires are only 6 months old) replaced crankshaft and MAP sensors changed out battery and alternator I also cleaned a bunch of things including the throttle body and IAC, which brings me to my... Oil in intake?
